Rsh uses only the source IP for authentication - which might be OK on 
well firewalled internal networks but it generally is not used these 
days.  The same concept will work from ssh too, where you can use keys 
for passwordless access.  Just
ssh host 'nohup command &'

On the other hand, if you'd like to be able to reconnect later with the 
same things running, you might set up freenx and use the NX client to 
connect.  That way you get a complete GUI desktop session that you can 
suspend (with everything still running) and connect back later.
