I don't know whether/how this is possible. The underlying WaitForMultipleObjects routine does not accept WinSock objects, to my knowledge (perhaps it does in Vista, with the rewriting of WinSock?).

It "works" in Windows 2000. I've got a variant of a prototype (and abandoned) Twisted Reactor that uses WaitForMultipleObjects for an alternate asyncore.poll() implementation on Windows. It sucks up 100% processor when sending trivial amounts of data from a single socket (where asyncore uses about 2%), but you do get the data.
