For what it's worth, I'm interested in having alternative project-list tools that more or less cooperate.
But I really think the project data should be editable on-wiki, for various reasons (one of the larger reasons is that tags should be flexible and easy to change, another is that if some authors don't post their information, and I'd like to add it myself from the Apache logs, if only to get the ball rolling).
To try to make the on-wiki data easier to access, I've made TSTOC able to dump its data. Running this will print to STDOUT the on-wiki data in a format like Leon's ~/.projects/.
/home/interiot/public_html/cgi-bin/tstoc --dump [--purge]
I would be happy to tweak anything regarding data dumping to accomodate any use of the dump.
Again, the data comes from http://meta.wikimedia.org/wiki/Toolserver/TStoc, and it's recently been changed to a format that's hopefully more accessible and easy to use (thanks for the suggestion, Nichtich).
