ok, IT's long past time to update this first post of the thread to avoid confusing people......
Witter is a full featured twitter client written in python.
It aims to support as much as possible, currently that is
main timeline, mentions, dms, search, trends, public timeline, user history (see a specified users last 20 tweets)
it supports bit.ly url shortening (if you have an id) and also will give domain hints for bit//ly urls expanded into brackets inline with the tweet.
It also has some support for uploading pictures via twitPic.
etc, etc
the latest info on versions and a full change history is maintained on my blog
http://danielwould.wordpress.com/witter

it can be downloaded from Extras here:

Generally speaking I try not to break the version in extras-testing too much, but do frequently break extras-devel version so only go there if you are prepared to figure a few things out.

if witter fails for any reason, then please run it from x-term like this:
run-standalone.sh python2.5 /opt/witter/witter.py

this will put lots of information to the terminal which I will need to figure out what I broke.
