Test OpenGrok installation (LXR replacement?)

Hi, Since LXR hasn't been updating since the shift to SVN, I've been investigating bringing it back. Today, though, I came across OpenGrok which appears to be a far more modern implementation of the same thing, using Lucene as the back end. I've set up a test installation of it at http://php-og.mgdm.net if anyone is interested in playing with it. Advantages seem to be: * It's really quite fast * It has a nicer UI, in my opinion * It's not too hard to set up * It handles multiple branches *relatively* well * It does incremental indexing, which I don't think LXR does It has the potential disadvantage that it requires Tomcat, which means running another web server somewhere, but I'm quite willing to volunteer to look after it if we can find a php.net machine to put it on at some point. For now, the test install is updating each branch from SVN and reindexing once every two hours. Any comments? Cheers, Michael
