Extra Slot [L4d]
 

I know this is likely to be impossible without the SDK, what i wanted to know is would this be possible once the SDK is out?

Im talking about adding a 9th slot to a l4d server ( or a 5th in coop ) that is spectate ONLY, hidden from the public, so that an admin could join and spectate the server. as currently its a real pain in the ass to admin l4d servers.
