That's the most amazing and interesting stuff to be able to create an all-have-fun USRP box where you can play with Airprobe and with OpenBTS, spending also less money :-) What if in such box you put a 52MHZ clock, would it break something respect to DBSRX card usage or would be independent (considering we'll find the right patch set) ?
