There was a demo of the board at Dayton, I was lucky enough to get a demo while we were setting the booth up. The demo setup, if I remember correctly, was using two SDR-1000's. I didn't find the delay noticable at all. Propagation delay is much more of an issue for HEO. 

BTW, the SDX sounded FANTASTIC! I had goosbumps when N4HY tuned to the beacon :)
