Haha, sending data using Giga Ethernet, nice idea!

What about cutting down the small low-power PC, and have the USRP talk
directly GigE ? Cheap interferometer anyone?

There's a page at http://comsec.com/wiki?USRPnotUSB discussing about
that. So far, there's no design, only ideas.

Matt, do you think there's enough spare I/O in the FPGA for 24 signals
at 125MHz ? RGMII can cut half, but signals have to be DDR which may be
a problem. How many gates are left? Enough for a stripped down MAC?

All the best with your exciting project,
