[Paraview] default_servers.pvsc question

[Burlen Loring]

going back to your original question. when exec'ing new processes there 
are various flavors of exec, including one that uses your environment. 
Which made me wonder which flavor is PV using? I wrote a little pvsc to 
test this out(attached). Apparently PV does use the exec that includes 
your environment. So if you want to use the ssh that's in your path, 
don't give the path in your pvsc, in the example you gave change it to

    <File default="ssh"/>

duh! (directed at myself)

I hope this discovery doesn't derail our discussion because the other 
features about being able to get information back from the server side 
we are discussing would be useful.
