Look at TF2 and you'll see how Valve extensively uses their database backend: achievements, player statistics, persistent inventories, etc. Even some sort of cheat evidence collection can be imagined having SQL support to QuakeC.
<paranoid>Also, from the security point of view is better to use a sandboxed persistence system under the form of a SQL backend than granting file I/O access to QuakeC. </paranoid>
I know FrikaC made a cgi-bin version of the quakec interpreter once and wrote part of his website in QuakeC
