Seems easy enough.  Use perl and the server port.  If your perl script 
detects DHCP is now up, then it could send a basic APRS message to the 
server port saying something like "Turn Interface 0 ON" or "Turn 
Interface 0 OFF", scince APRS data sent to the server port is never 
gated, then only your box would see it, and you would get a message 
notice telling you that information.  The parser would only start 
interface 0 if the sender matched an internal ID code, like Callsign-PL 
or whatever.
