A question re: BTSync/RPi - I've got around 40-50 gigs synced up between my x86-64 computers (might be on the order of fifty thousand plus files) and the maximum memory it occupies is around 60-70 megs. It idles at 42MB. Since you already have the set up that I am looking into, I think you're the right person to ask, can the RPi handle that much? If not, what are the signs of it slowing down? If it helps, my hypothetical RPi would be connected via wires instead of USB-Wifi dongle.

Looking at it, I have about 10k files and it is only using about 12% memory, perhaps not as bad as I thought. 50k should be absolutely fine I would think. Here is the output of top showing btsync at idle:

    PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
    2993 btsync    19  -1  122m  60m 2988 S  11.9 12.4 610:05.84 btsync

I have noticed that the CPU takes a beating during any sync operations, tends to grab 100%. I limit the CPU for the btsync process to 60% max and also overclocked the Pi up one level (after installing a heatsink kit). Here it is during typical filesync operations:

    PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
    2993 btsync    19  -1  122m  60m 2988 S  63.8 12.4 612:51.33 btsync

To limit the cpu I use cpulimit and put this in my /etc/rc.local

    /usr/bin/cpulimit -e btsync -l 60 -b >> /dev/null

Sweet. I guess I'll be ordering one after all. And thanks for the cpulimit code as well. I had no idea you could do such a thing at all.
