That was weird, I got your original via USRP-users even though it wasn't on the To: list…bcc?

What I’m more curious about is how easy it is to build a single GR flowgraph that mixes GR processing with FPGAs that live either in Zynq or connected 3x0 series devices. It sounds like this kind of support is an explicit goal of RFNoC.
So if you are asking can RFNoC create arbitrary paths in a flow graph where data flow passes Host-based-GR -> FPGA -> Host-based-GR, then yes, that was one of the original architecture goals.
