Witty for Identi.ca. Only the brave need apply.
If you have a Windows machine with VS2008, .Net 3.5, svn and patch on it, you can get the source for Witty here [1] and a patch [2] that will make it run against Identi.ca
Witty can talk to Identi.ca
I am hoping that I will be able enable both services at once so that I can view tweets/notices at once.
