Hey Steve, so, how much sampling rate do you need? If this is a local network, directly using the USRP from Windows might just work. But: An X310 can generate significantly more data per second than fits through gigabit ethernet, so this can even theoretically only work if sampling rates are relatively benign (i.e. below ca 30 MS/s). So: What's the sampling rate you and your colleague are trying to achieve? WHat's the network speed?
Also note that high rates, no matter how you encapsulate these, will put a high load on your router - and that might or might not work out well.
