What about using GNU screen?  You add

 -start_in_debugger -debug_terminal "screen -X -S debug screen"

while having a screen open on the node with "screen -S debug".  When the
processes launch you will get new windows open in the screen session.  Of
course, you'll need to be running on a single node unless there is some way
to attach to a remote screen.
