@whig, atm no. We are soon opening some APIs that are compatible with twitter so it should be relatively easy for developers of tweetdeck and similiar apps to add support for qaiku if they see it appropriate. And changes are if they get enough feedback from their users they just might go for it.
I just know how to make little PHP script that shows my qaiku's (takes them from RSS feed) on my homepages =) I hope that somebody who knows how to code write Qapp.
