That's what I'm thinking. But encrypted or not, anyone who copies it 
will have access to the software.

(I'm starting to wonder if I care...) ;)

When the software is installed on the server, it gets the MAC address by 
itself and stores it. The issue arises when a copy of the software on a 
remote machine starts up and needs to cross-check with the server to see 
if the server is running a valid copy. I need the server's MAC address 
for that.

Note that no software will be installed on any client machines. 
Everything has to be read across the network.

Storing info in a file that can be read remotely seems to be the only 
way to deal with the problem, but then that leaves a hole in the 
security. Anyone who copies that file and installs it on a different, 
unlicensed network will have full access.

The text file, encrypted or not, needs to be hidden and inaccessible to 
users while still being accessible to a remote machine inquiry.
