Well, between other tasks, I'm slowly working on it. FogBugz looks interesting, but I can't justify $129/seat. There are things I like better about Trac, including open source Python, integration with Subversion, and built-in Wiki.
The problem right now is getting it to work with Python 2.4; apparently, the Subversion 2.4 Python bindings haven't been done yet, so I'll have to compile them myself. I won't go back to Python 2.3.
