Is there anybody out there to help me with this idea:

From the empeg menue I would like to have something like a menue entry which sends a command over LAN and starts an application on my home PC.

Background:
My empeg is connected over WLAN to the home network. But the empeg is only accessable when not powered down.
On my home PC I have a script to convert routes for gpsapp and tranfer them automatically via ftp to the empeg.
When starting in the morning I calculate the routes but then have to go to the garage, start the empeg, go back to the PC and start the script to transmit the routes.
This is the process I would like to shorten by sending a command from the empeg which starts the script on the home PC automatically.

Any idea on that? Are there any standard applications for that purpose?
