In light of the recent events of SourceForge employees hijacking the project download areas and adding adverts and adware onto Windows installers, I would think that this is a bad idea. If you're making the decision due to an affection with Subversion, that's not a sound decision, to be blunt.

You should use the best technical solution, and that's Mercurial or Git at this time. I'll have...issues and concerns...if you guys move it over to Source Forge (As an observation, prior to the incident, I'd probably have just grumbled and let it go without comment. Now, however...)

Right now I'm not using it extensively, but with the latest versions and the stuff showing up in the Bazaar that make it worth considering for app development...I'd hate to see the project make this sort of mistake right now.
