The problem is: SSL is *NOT* usable for virtual hosting. You need an 
separate socket for each SSL vhost, so you'll probably prefere 
several independent httpd's - maybe then stripped down w/o any vhost support.

Aehm, what exactly do you want to do ?

Measure users's consumed traffic ?  (-> logfile ?)
Measure users's consumed bandwidth ? (eh, does this make sense at all? )
Limit user's bandwidth ? (very complicated w/o proper kernel support)
