I tested that using a TCP/UDP source/sink for bigger iron to connect to.
(USRP Source -> TCP Sink, TCP Source -> USRP Sink)

Better results than I expected. At native speed, I was able to do 250kHz 
full duplex, with very few under/overflows.

I'm convinced that if I'd overclocked it, then it would have been
fine. This was on an original model B with only 256Mb of RAM, the
B2 models with 512Mb I haven't had the chance to test with gnuradio
(yet.)

As far as special build instructions go, I followed a post on this
list, and everything built fine. I don't know if the "extra" ./configure
flags etc have made it into the build system.
