Also technically I guess (IANAL) you might have to prove that you obtained the source code prior to the license change. We like to say code itself is licensed such and such, but in reality code is licensed to somebody. If you just place the code somewhere for a month with a license next to it and take it down again, and somebody later comes and wants to get those terms, it's probably too late.
OTOH please correct me if I'm wrong. Law contains many unintuitive things like contracts by handshake and so on :-)
