Note for bug system on eureka: Should have CUSTWAIT and possibility for all logged in users to comment on all bugs.
Are bug tracking systems hosted, administered and developed by a third party passionate and focused on improving the bug tracking system (and competing with other bug tracking systems providers) a non-option?
Bug Crunch has sucked approximately equally much since its inception (when it was a little better than Bugzilla), and I think we have every reason to believe we won't spend more time and effort on improving Bug Tracker TNG, once installed, either.
I have a distinct feelig there are systems available today that meet all the criterias "free or cheap", "has no lock-in", "integrates well with CVS, Subversion and/or git" and, perhaps most importantly, "kicks ass, for getting things done". I find it likely that several (or most) also offer web hooks, allowing us to still hack our own cool extras to tie into the system (if we want to).
