I envision some number of data streams to/from the USRP, each with
it's own destination on the host. They then could each have
over/underrun flags.
If it's mainly about tx vs rx, or separate data streams, then that's
something that could be muxed on udp port.
This likely requires a lot more thought.

Sure - I was thinking the same thing. The requirements document
probably should say "local bus attachment".
