I'd really like something that integrates with Lighthouse, or possibly Trac.
I've tried Codesion but for some reason, the permissions just didn't seem to work at all (a user was able to commit to a folder they had no access to) and have generally heard unsatisfactory things about them.
Tried Codespaces which handled folder-level permissions fine, but doesn't appear to integrate into anything.
Beanstalk is nice, but no permissions management.
If there are no "perfect" hosted solutions out there, I'd settle for a web-based SVN management tool that allows full control (including folder permissions to restrict certain groups from access to QA/Production areas etc) which I can then just drop onto a server of ours and integrate directly with Trac.
A fully hosted solution is ideal though. Hugely grateful if anyone could point me in the right direction.
