Workflow/Script for Twitter shortURLs?

Has anyone developed an applescript workflow to deal with twitter links? Specifically, I’m looking to store the final bookmark referenced in a tweet into DT, after decoding from the shortURL…

Here’s a little example but it’s not that fast as it’s downloading the main resource/page of the destination page.

tell application "DEVONthink Pro"
	download URL "http://..."
	set theForward to last downloaded URL
end tell
