Source Forge does have a web CVS browser that I've used in the past to paste 'links' to code. But displaying code in a "code node" would be tricky. Also you'd need a repository for such things, of course it could be an existing repository under something like "ptkdb_pm_code_nodes"
What I was thinking about was that at a certain PM level here, you would get a repository, and that code node displays could be drawn from that repository to allow monks to update code in response to commentary, votes, etc.
anyone else think it's fun to say 'code node'?
