[kepler-dev] VNC for 'detached execution' of Kepler?

Dear all:

Steve Parker just mentioned the Virtual Network Computing Package.

This could provide a (simple?) solution for some of our Kepler/HPC
activities, i.e., where one starts a long running job and where the
control instance/workflow engine (Kepler/Ptolemy) needs to continue to 
run as well for a long time.

So here is an example:

Someone wants to start a long running workflow/computational
experiment (say via Nimrod, Condor, etc) from the laptop. 
Obviously, after disconnecting the workflow needs to continue to
execute, and one should be able to reconnect to the running instance.

By starting Kepler remotely on a "Kepler/Ptolemy engine server" (not
necessarily the compute nodes, mind you!) and routing the display etc
through VNC, it seems the above can be done (disconnect and reconnect

So this is a bit like Citrix++ but for "real systems" ;-)

Just a thought..
