If this is allowed (I remember that psychonic removed compiled extensions at some thread during SteamPipe beta, so I don't know..), here is windows build.
Can't test it, because on Win I have only test TF2 server, but for TF2 callback shows same ID's (and its my account UID), so I think it works. Later I will install CSS server for tests and check this ext.

UPD: Tested on CSS Windows. Works fine.
