I can't seem to solve. If someone can run my software on a USB thumb
drive and run it on different computers, what's stopping someone from
copying the software and giving it to his 10 friends? How do I detect
it? I could have a web server that the program contacts once a month
or so which could invalidate the license (program stops running) if
it could detect if the software was being run by an unlicensed user,
but how would it distinguish beteen a valid user running the software
on 10 of his machines (internet cafe, office computer, home computer,
laptop etc), or 10 different users running the software? Is it
possible to get a hardware id from the USB drive and lock it to that
piece of hardware? Or should I lock it to the machine and if the user
want's to run it on more machines, offer to extend the license to 2
or 3 machines?
The most successful one I saw involved contacting a central server to
"get" a license, however, thats not always a practical answer.
