I had an idea in the shower. Would it be possible to write either a CGI
script or a Javascript page that can do a history of sorts for Wiki Wiki? It
could load up the 
http://www.c2.com/wiki/history/
pages and the recent posts
pages and perhaps reconstruct the edit history for a page.
This would be really tough to do from an external server, so it's probably infeasible. But if I actually implemented it, it would be really cool.
