That's the scheme I have in mind for making a Pertec interface one of these 
days. Of course, that's far down on my list of projects, so I won't complain if 
somebody else gets around to it first, and shares the hardware and software 
designs.

I was previously planning to so that, and I still think that the FPGA approach 
would feel more natural to me than using the PRUs. But the Beaglebone seems 
like a much more economical approach. I'd need a processor to control it, an SD 
card and/or USB and/or network interface to get data and commands on and off, 
and driver stacks for all of that stuff. I could also get there with a Xilinx 
Zynq family device, but at 2x or more cost vs. a BeagleBone.
