This procedure is not equivalent, except in the long run, to the kind
of license Fred Trotter wants, because its effect on particular copies
is different. Suppose that Alice sells Bob the source code to Yoyomat,
a proprietary program with delayed GPL. After the term has passed, Bob
may now distribute *that very copy* of Yoyomat freely to Charlie under
the terms of the GPL. In the scenario you outline, he may not; he must
obtain a new copy from the escrow agent.

But surely the conditions associated with the permission may include the
effective date. If I post a sign on my land today saying "Hunting and
fishing permitted to all after September 15, 2013", then I may revoke
that permission at any time, but if I *don't* revoke it, surely anyone
can hunt or fish provided it is after the date mentioned.

The transaction costs of doing so are lower. Granted, I could take down
the existing "No hunting or fishing" sign on September 15 and put up a
"Hunting and fishing permitted to all" sign, but perhaps I won't be
there on that day.
