This does not apply to webspeed but is an operating system issue.. What opsys are you running ?
If unix, you could do a rlogin and start the application. For how to run opsys commands look in the manual (Hint: OS-COMMAND or UNIX or DOS etc.)
Another thing you could do is to run appserver on the other machine, and connect to the appserver from the webspeed-code and run whatever needed....
Kind regards
