For now, NX or FreeNX have no way to discover and react on a condition
where the NX session display window is mininimized on the NX client.

If the applications you use (screensavers, clocks, system monitor applets)
produce lots of X11 network traffic, there is nothing NX can do about it
but what it does now: compress the traffic, reduce roundtrips as much as
possible. There is no known method out there in the wild which does a 
better job at that than what NX currently does. If this is not good enough 
for you, bad luck  :-|

But I still somewhat doubt your figure of 50 kbyte/sec (which is 400 
kBit/sec) for a screensaver...
