I know that some people use ssh as rsh_command, which may have similar problem?

As the grid(s) get closer and closer to the enterprise I'm starting to see software developers and others trying to play games and then plead ignorance when asked "why did you SSH to a compute node and start a tomcat service out of your home directory?". heh.
