I have a usrp and computer in a remote location without much network

the results to a connected client for display. This would allow me to
get greater fidelity than xwindows forwarding or the ascii dft example
while also using less bandwidth. I would imagine the client side
would potentially reuse some of the existing wx or qt interfaces for
display and control.
This seems like a pretty useful / simple use of this hardware. Does
anybody know of any implementations floating around that does this?
I'd prefer not to reinvent the wheel.

You could use a GRC-based flow-graph that computes the FFT, and outputs
the results to a FIFO, and have a small C program that simply puts
"snapshots" in an appropriate place. Once it's in an "appropriate
place" (and perhaps in a form that you like), you could use a web server
to observe the results. Roughly 1e6 ways of skinning this particular
cat.
