I'm very intersted in this project and will help to make things happen. I can help in any part of the design, but I have more experience in FPGA developing.

Hi Marcus,
Who works on this project now?
Nobody, really, except that I've posted a few "straw man" designs.

Why choose USB as the interface to host. The USB interface became the bandwidth bottleneck
in USRP1, so why use network interface?
USB-2.0 is relatively cheap to implement, which is *one* of the project goals.

Using 8-bit samples, you can achieve roughly 16Msps.  Using 4-bit samples, you can do better.
  4-bit samples reduces your dynamic range, but for certain high-bandwidth applications, that's
