Linux Game Publishing Copy Protection

The keys are stored on an internet server and retrievable by entering a name and password
LGP claims one can install and run the game without an internet connection, copy the game for personal use, install the game on multiple computers for personal use, freely transfer/buy/sell the right to use the game (tools to assure buyers of getting a legitimate copy are provided at the website), key/name/password are required only when installing or making significant changes to your hardware, and all this can be done without the original CD (which is touted as an advantage to the customer).
