I think there are a million ways for solving your problem. It depends on what exactly \
you want to achieve. If I were you, I would write a shell-script to check for running \
roxterm instances, and if there are already enough instances switch to one, instead \
of starting a new one.

Simple example (you probably need to change it to your needs):
#!/bin/bash

ROX_INSTANCES=$(pgrep roxterm | wc -l)

if [[ ROX_INSTANCES -gt 5 ]]; then
  # we have more than 5 instances already open, so switch to the first found
  wmctrl -a "roxterm" # roxterm is the window title, I have no idea, how the real \
window title of a rox term is ;) else
  roxterm
fi
######## End of example ###########

It really depends what you want to achieve. For me wmctrl sometimes does not work, so \
I use wmiface instead sometimes.

If you clarify your request a bit further, i.e. what do you mean by too many \
instances, what do you expect to happen, etc I could help a bit more ;)

Andreas
