This is exactly what I'm doing. I have a diskless sp13000 with a pvr-150 as a combined frontend/backend next to the TV where all the terrestrial & sat cables are and a server with all the noisy disks locked away out of earshot. Works like a charm. I'm using standard 100M cat5 cable thru the house and even though the live TV ring buffer is on the NFS mounted server, I have no issues at all with it. Since I've only got the system up in the last week, I've not done any CPU timings but the lights on the 100M ethernet switch only twitch during live TV when data is going both ways so its not stressed at all. I'd guess (based on DVD & divx playback) that I'm using about 50% of the CPU time when both back & frontends are running during live TV.
