What is the best solution to scrape many prices from many different websites?
Is it possible to scrape prices realtime? If yes how?

I don't know if it is still being maintained, but I've found scRUBYt to be very useful when it comes to scraping. http://scrubyt.rubyforge.org

Any way of doing the described in this question in iOS?
NSTokenField with mixed token/string input, possible?
As you probably know there are no equivalent Classes for iOS, anyway there are a couple of project around that do this pretty well, for example TITokenField. You can use the control as it is or grab just the logic behind.

I build an app in RoR which is on heroku. And I want to send a fax every time an order is taking place. What will be the best option for me?
Thanks
You could use InterFAX or eFaxCorporate. I don't think any of these APIs come pre-integrated with Heroku though. The use of InterFAX from a Ruby environment is documented on this book.
