iOS Hardware UUID

How are companies like testfairy capturing the hardware id of iOS devices? This is something I've wanted to do but have been continuously been directed towards using the currentDevice.identifierForVendor.
You need an Enterprise Developer license from Apple, then you generate your Enterprise certificates. Once your enterprise certificate is in place, your tools and libraries should be able to get the actual device UUID rather than a dynamically generated UUID at install.
You can read more on the Apple Developer Enterprise Program and the associated Distributing Apple Developer Enterprise Program Apps. During this process, you will probably want to open a Technical Support Incident with Apple to get the gritty details on how to do just that. But at least you will be on the right path.
Good luck, the work is easy, finding how is challenging.

Host my .ipa app file on private server and download without developer license

I have an iOS app that I've made using a free provisioning profile, in order to give the app to people though, I have to plug their phone in to my computer and install it with Xcode. I was wondering if there was a way to let people download the app from my server without paying for a license.
No, the only way to do this (install on another person's device without having their device set up explicitly in a developer profile) is to use an enterprise development account. This type of account (which costs even more than the $99 standard developer account) allows you to create an enterprise distribution profile that allows for distribution on devices that have not be set up in advance. However, the enterprise account is even more money and you must have an EIN (like a SSN for companies).
So to answer your question, no there is no way to do this.

Only certain devices allowed to use enterprise app

could I potentially require UDIDs for internal distribution as well?
Currently, I sign the .deb file and install the resulting .ipa file on every single iOS device myself. I only have a normal developer's license, and now I am thinking to get the enterprise license in order to speed up the process of installing the in house app. It's important though that I am able to limit the devices that use it to prevent it from leaking.
Last but not least, with the normal developer's license the app stops working after 365 days and it needs to be resigned and reinstalled. Is this the same behavior with the enterprise license and the in home distribution?

iOS kernel development

What is the process (if any) to develop to iOS Mach (kernel) is there is something similar to Windows when you develop a driver and Microsoft Sign your driver?
can it be distributed via the app Store?
The iOS kernel does not directly support loadable modules even from Apple as far as I'm aware. Jailbreakers have at various points found ways to modify the kernel, but I don't know what the current status of this is. In any case, even if you figure out how to do it, Apple will not allow you to distribute iOS apps that hack the kernel.
On OS X, there is an official way of distributing kernel modifications: kernel extensions (kexts). From OS X 10.10 on they must be codesigned (10.9 issued a warning if not, so highly recommended even there). To sign a kext, you need a special version of the "Developer Id" (gatekeeper) certificate: you need to be a member of the developer programme, apply for the kext signing certificate (you need to provide a valid reason), and wait for approval. If and when you are approved, you need to request a new Developer ID certificate from Apple's certificate provisioning portal, and finally use that to sign your kexts.
Note that the Mac App Store rules specifically forbid distribution of kexts, so you cannot offer kexts or apps that install/load kexts in the App store. There's a possible loophole in apps that offer a plugin interface. If a user downloads a plugin for a Mac App Store app from outside the App Store, then that plugin can load kexts, as far as I'm aware.
Note that there is a kext tag on StackOverflow which is specifically about OSX kernel development.

Is it allowed to resign appstore apps for enterprise distribution?

My manager is asking me to get an app (free app, not our app) from the appstore and resign it with our enterprise account and distribute it with our MDM tool.
Is this allowed by Apple?
Or will this possibly result in our enterprise account being terminated by Apple?
every app has a specific code given by the app store which even if resigned CANNOT CHANGE...it it the same as how youtube identifies reuploaded videos and informs the actual copyright owner...apple's t and c clearly state that it may result in being banned or complete account termination
a statement from the t and c
(vi) iTunes Plus Products do not contain security technology that limits your usage of such Products, and Usage Rules (ii) – (v) do not apply to iTunes Plus Products. You may copy, store, and burn iTunes Plus Products as reasonably necessary for personal, noncommercial use.
rules ii-v are simply not required here
