Adding new winsock functionality (overlapped) in Windows NT

[Skywing]

I was having a discussion with several people in the channel recently about implementing overlapped versions of connect and accept (with completion routines) in Win32 (specifically, Windows NT).  It would be nice if these could coexist with IoCompletion objects created by CreateIoCompletionPort.

How would one go about doing this?  Perhaps installing a filter driver to intercept requests to Afd.sys?
