Hey Will,
CC'ing the development list.
Yeah, we do have a sort of dilemma with license transfer, don't we?
Release() doesn't work like you think.  It was intended to be used in
conjunction with Acquire(). Right now it's just a stub, but it's use
will be more apparent when we implement concurrent/multi-user licensing
enforcement.

I can't think of how we can do it with the current version. We'd have to
build some new features into AL, like introducing a new property to the
license file called "Valid" or something, and provide an API for you to
turn it on/off. What do you think? Let's brainstorm....
Also, this won't stop them from using the original liberation file to
register the second time. So we'll probably have to include some sort of
expiration period into the liberation key. i.e. you must register that
key within, say, 7 days from the issue date, otherwise it will become
useless.
