Caching things is harder then it may appear. There's two web servers, and several dozen (most likely) httpd worker processes on each. Any update can go to any of them, and is then reflected on the DB server. It's difficult, then, to invalidate the cache intelegently, unless it's done on the DB server. If it's done on the DB server, which is very loaded, then it needs to be /very/ tight code, or it's not any better then intelegent use of the DB, which we already do.

Also, we aren't set up very well for making modifications to, or additional code to run on, the DB server, because such code isn't nodes in Everything.
