i've been fiddling with OpenGrok, the OpenSolaris source code browser:
http://tools.wikimedia.de/source/xref/
maybe it would be nice to use this to publish the source of people's tools (it does cross-referencing, searching and so on as well as browsing).
anyone interested?
(downsides: it doesn't support PHP; but that shouldn't be too hard to add.)
