You mean SL isn't running on a DB already ?!?

Assuming it's running on Apache, you could use mod_rewrite to have 'normal' URL converted to parametrical ones on the server side of things. It should allow spidering of your site while allowing you all the goodness you can do much easily with a DB.

Heck, even my personal site is running on a MySQL DB (with Apache server and php as the language of choice FYI).
