Hack and /or Feature Request

Anyone currently running a karma engine with geeklog?

If not, maybe we could get this intragrated into the next version of geeklog.

Cache, does anyone have a hack, mod , or idea how to get the following ported over from dacode.org. they sue a file called gen.php3 which is called by the index to create a tmp file so visitors see http://www.foo.bar/topic,1,0,10,1,02.html. vs http://www.foo.bar/index.php=topic

Its this feature I am really intrested in. The same sort of advanced caching is used by zdnet and wired along with others. Its the kind of feature that would put geeklog lightyears beyond the rest. Even through its above the rest (imho).
