Capturing twitter status timeline updates/infinite scroll updates - twitter

Question

I'm using KRL to inject elements into twitter timeline statuses similar to Jesse Stay's TwitterBook. The problem I have is that these elements are only associated with statuses that are currently visible when the bookmarklet is initiated. If a new status is added through the 'new tweet' updated via Ajax or through status updates via infinite scroll, these new statuses are untouched.
Is there a way to either poll for new statuses or sense a twitter status update event via KRL in order to inject elements only into those newly added statuses?

The example posted at
http://kynetxappaday.wordpress.com/2010/12/25/day-21-modifying-facebook-stream-with-kynetx/
works with the Facebook stream but the concept is the same
create setTimeout infinite loop to look for stream items
only select stream items not marked as processed
process stream items
rinse and repeat
Code example from post
ruleset a60x512 {
meta {
name "MikeGrace-status-update-translator"
description <<
MikeGrace-status-update-translator
>>
author "Mike Grace"
logging on
}
global {
datasource insult:HTML <- "http://www.pangloss.com/seidel/Shaker/index.html?" cachable for 1 second;
}
rule find_status_updates_by_mike_grace {
select when pageview ".*"
{
notify("Starting to look for status upates by Mike Grace","");
emit <|
// get app object to raise web events
app = KOBJ.get_application("a60x512");
// function that finds FB status updates by Mike Grace
function findMikeGrace() {
// loop through each stream item on the page that hasn't been processed already by the app
$K("li[id^=stream_story]:not(li[kfbt])").each(function() {
var currentStreamItem = this;
// grab the current stream item posters name
var name = $K(currentStreamItem).find(".actorName").text();
// mark the stream item as being processed to reduce future processing times
$K(currentStreamItem).attr("kfbt","y");
// is the stream item by the perpetrator?
if (name == "Michael Grace") {
// strikethrough the original update
$K(currentStreamItem).find(".messageBody").wrap("<strike />");
// get selector to return translation of status update
var returnSelector = $K(currentStreamItem).attr("id");
returnSelector = "li#"+returnSelector+" .messageBody";
// raise web event to get translation for non geeks
app.raise_event("get_insult", {"returnSelector":returnSelector});
} // end of checking name
}); // end of looping through unprocessed stream items
// call myself again later to process new items on the page
setTimeout(function() {
findMikeGrace();
}, 9000);
}
// start the process of finding the perpetrator
findMikeGrace();
|>;
}
}
rule get_insult {
select when web get_insult
pre {
selector = event:param("returnSelector");
insulter = datasource:insult("#{selector}");
foundInsult = insulter.query("font");
singleInsult = foundInsult[0];
}
{
emit <|
console.log(singleInsult);
$K(selector).parent().after("<br/>"+singleInsult);
|>;
}
}
}
