simple rsh and python question

[Randy Wadkins]

Is there any way to rsh from a shell script to nodes in a cluster and
execute a python script that will run in the background on each node? 
It appears that the execution is stopped once the rsh command is
completed.

I'm thinking something along the lines of:

for x in node1  node2...(etc.)

do 
  rsh x$ python myscript.py "&"
done

but, the above doesn't really work.  The python job is terminated
before completion.
 
Thanks,
