Re: [Discuss-gnuradio] The coming deluge of CPU cycles

I'd vote for Gigabit Ethernet as an interface.  It offers the following:

1. Place the USRP very close to the antenna.

2. Distribute the signal to multiple computers. (Multi-cast IP)

3. Very low cost infrastructure of Ethernet switches and cables.

4. Ethernet is easier to use across common platforms like
Windoze/Linux/Embedded systems.
