Do you have a lot of experience with fsfs with svn 1.1.3? Personally, I haven't found any defects in bdb svn. The only reason I have to switch right now is the assurance of the trac developers that it will make something more stable (they do not have a good track record in this department).

If we decide to do this, some tickets will probably appear in the tracker. I'm sure you'll notice them. :) Thanks for offering to help.

Stability and limited usability. The only real killer feature trac has is linking from the wiki to the ticket tracker to the svn browser. Each of these independently is only okay (the ticket tracker on its own is pretty lame), but cross-domain links are handy.

As an issue tracker, roundup is at least as good as trac, I think. As a whole website dealie, trac clearly has a bit more going for it.
