You can take this one step further by picking an always-on host where 
you run freenx.  Then connect with the NX client from www.nomachine.com 
and start a desktop where you can park long running jobs like monitoring 
tools (including remote X connections or a bunch of xterms with ssh 
connections elsewhere).  Then you can disconnect the NX client and 
reconnect later with everything still running.  The connection can be 
from any linux/windows/mac NX client and you get very good remote 
performance even over low bandwidth connections - and unlike normal X 
connections, losing the connection doesn't kill the processes.
