Have the program open a ServerSocket on a specific port.  If it is able to
open the port, then it's the only instance of the program running.
If it can't open the socket, either there are multiple copies of the program
running, or something else is using the port.  You can make the port user
configurable if you need to, as long as the program writes the new port number
someplace permanent
