I guess to keep it updated would be a pain as well...good idea though
Honestly not that big a problem. :p Very easily automatable, at least if planned for.
I could get a database knocked up within a few days and a few PHP scripts knocked up in a week or so.
It's just I have no idea how to integrate search forms into PHP scripts, which is a ridiculous hole in my knowledge that I am now ashamed about and must rectify.
