I wrote a voting module for LOX and published the source. It is strictly for map voting but the hooks are there for other vote types if someone wanted to extend it. LOX was derived from early WOD so it is fitting that she returns something back to her cousins in WODland.http://www.clanwos.org/forums/viewtopic.php?t=3984
The whole module could be put into a proxy DLL along the same lines as q2admin and it could be stacked into a mod like WOD 8 just like q2admin was if someone wanted to simplify the task over trying to untangle the Q2admin voting code. Avi Zung's GameCam is a model of good server proxy DLL hooking for those coders who might be interested.
Assuming, of course that Rich was unable or unwilling to add it to the engine. Extensions like this are usually reserved to the game dll to implement.
