Aha! Well the RSP can be hosted on any machine (win7 VM), and offer it's I/Q data stream on UDP to the crunching machines. If you want to configure many many crunching machines, maybe the I/Q stream could be forwarded by multicast. (I'm guessing IP not Ethernet. Although that would interact with MOSIX process migration, which would have to cover IGMP join and leave... Maybe it does already?) Interesting project!
