[Paraview] Trouble running Paraview OSMesa in parallel on cluster

[Cook, Rich]

We have a tricky firewall situation here so I have to use reverse tunneling per http://www.paraview.org/Wiki/Reverse_connection_and_port_forwarding#Reverse_Connection_Over_an_ssh_Tunnel

I'm not sure I'm doing it right.  I can do it with a single server, but when I try to run in parallel, it looks like something is broken.  My understanding is that when launched under MPI, the servers should talk to eachother and only one of the servers should try to connect back to the client.  I compiled with MPI, and am running in an MPI environment, but it looks as though the pvservers are not talking to each other but are each trying to make their own connection to the client.  Below is the output.  Can anyone help me get this up and running?  I know I'm close.  

Thanks!
