Freeware ports of the Unix tools to Windows NT and 95 are nearly completed. Versions of sd and sdr are available. Vat and vic can receive audio and video (respectively) and will soon be able to send also. There is no wb (whiteboard) or mrouted (tunneling) yet.

On the Mac, QuickTime Conferencing (QTC) is being extended to make it work with the MBONE. Right now it can receive from nv and vat. See http://www.devtools.apple.com/qtc/ for more info.
