Since the E100 runs a "normal" linux, yes, it should be relatively easy.

No, no way. You can of course use something like a network sink in GNU
Radio, but that won't be fun (100Mbit/s means even for 8 bit samples
5MS/s max, and that's more than the CPU on the E100 can feed from the
Radio to the network).

Use the N200. It's the right device for that job!

Best regards,
Marcus
