Re: Is there some sort of portable Copy Protection??

You should try AntiDuplicate http://www.alkonost.com/antiduplicate/

With AntiDuplicate you prepare hardware keys (dongles) from your ordinary USB
flash drives! Each instance of your program protected via AntiDuplicate has a
key USB flash drive, that must be plug into USB port when your program is
running.

So user can go with his USB flash drive to new computer and your program will
still work. It won't work without protected USB flash drive.
