custom rewrite queries

Hello all,

Offcourse the custom url rewrites are a great addition, however, there are alot of hacks which uses an id parameter of some sort.
In this case the rewriting is only usefull to make it appear as a static page.

What would be a great addition IMHO, but also rather complicated i suspect, if we could insert a custom select query which grabs an title, instead of using an excisting id parameter. This way it could create truelly an content relevant url.

What do you think?
