Very nice. I've been using Redmine, and it's working but I can't really recommend it. Would love to see this. Kicked in some dough.
Name something else which we can customise, make client facing easily, have AD authentication working against, use for documentation, source tracking, ticket mangement and infrastructure management with an administration effort of 30 minutes a month at average, that costs $0?
Trac is a framework which just happens to have ticketing, wiki and source control modules.
Redmine is a ticketing tool, wiki and source control browser which happens to have half a framework underneath it.
Its a Redmine Fork invested a lot of time into cleaning up the whole thing.
