I get that, so what is a feasible sample rate?

Probably not much, since there is no USB hardware, everything need to be done in software bit-banging, like done with V-USB on AVR.
According to V-USB site, probably something like 24KB ...

I don't even know if trying to port V-USB on ESP can be achieve due to nature of WiFi background thread.

Interesting; thanks. I was reading the WIFI takes ~ 20% CPU. I guess I'd have to look at a intermediary chip to packetize the information on the usb and make it easy to process. At that point I'm probably looking at an FPGA and then I might as well just use the ESP as a wifi module. People use RPi's as SDR servers for like 4 dongles I was hoping to find a platform that was more embedded for just one... Edison is intriguing but not exactly saving money either. thanks .

You can also look at other RPi formfactor boards such as OrangePi-PC or even the newly cheap OrangePi-One (at $9.95), with those, you will get even more power than RPi.
