As I'm adding more committers to my open source projects, I decided it might be worth getting a dedicated mac mini for pyworks.org rather than sharing it with my other sites.
So I ordered another mini through macminicolo and it's up and running. I haven't switched over to using it yet, though.
I think I'll wait for Python 2.5 and Trac 0.10 and then make the move.
The original post had 4 comments I'm in the process of migrating over.
