When you set up a backend, you store two settings in the database, the 
local backend IP, and the master backend IP.  When the backend starts 
(and only that one time when the backend starts), it will lookup its own 
hostname, query the IP listed for that hostname, and then query the 
master IP.  If those two match, it will act as the master on that MythTV 
system.  The ONLY way that connecting your laptop to the network could 
make your laptop the master is if you had some script that changed that 
master backend IP in the database, and then restarted the first backend.
