Not sure how this would work without making the system online dependent to install games.
If I install a game on my console and then lend the disk to my friend and he installs it on his, how will the game know it has already been installed on another console?
If you go with an always online model then you will be able to implement a formal game lending system into the console itself.

I think it would be nice to give people a choice -- either play off disk to keep the game transferable or install to disk and lose transferability.
But of course the nice option is rarely taken by anyone.
That said, this wrinkle isn't my biggest gripe with the new or even current xbox -- peer hosting is.

It's claimed that you need to go online once per day with the Xbox One[1], so could revoke access during that connection.

In that case there's not much point bothering with the disk, just tell xbox live to grant your license to your friend for the next 24 hours.
