yes it is.  However, the problems are non-trivial to handle.  Network
bandwidth is _far_ less than memory bandwidth on a PC.  And on a PC, memory
bandwidth is not great itself, so you can guess how the net bandwidth looks.

if you mean machines connected over a WAN rather than a LAN, then network
jitter and lag introduce additional problems that have to be handled.

All are managable to an extent, but just not easily...
