A Global Unique IDentifier?
I've been using the memory address of where the ID variable is stored, as the variables value, for an ID number, but that only really applies locally. You could then append the ID of a computer to it, such as its IP address as an int, giving you a Long containing the IP address and the memory address.
Otherwise you could have one computer be a `GUID server` which generates a number and then sends the number to the other computers for them to use.
