I have tried it and had it working at a Hawk Host shared hosting account, though it was a year back or so. The installation is pretty straight-forward if you have Shell access. There is one thing though in getting the app to run properly from cPanel, but I cannot remember what it was. If you don't do it right there, there's a process that starts taking 100% of one CPU core and you'll have to stop that. Once that's been fixed it works perfectly (without local subversion, that is)!
But like I said, this was all over a year ago. Perhaps I'll try again soon and create a how-to, might be useful
Edit: it appears to work with external subversion repositories. That, plus it's multi-project feature, gives it a bug plus over Trac from that point of view.
