But that's not a problem is it? Listen, connect, send query, wait x seconds for responses, stop listen, repeat... Does Windows not provide an API for UPnP discovery? Certainly Windows Vista, which I'm currently playing with, has Function Discovery interfaces that do all this, Vista even found my Linksys wireless access point, mind it didn't find a proper display adapter and Vista is really painful in VGA.
