I know this is getting off-topic, but the recent discussions on this and
other apache lists regarding licensing has been extremely informative to me
(being relatively new to open source development).

Do you mean that if I were the sole author of a piece of software, and
released it under license A, then later decided I didn't like license A, I
could then re-release it under license B?  I guess I was under the
impression that once you released a piece of software under a given license,
that constituted some kind of implicit contract between the author and any
users, and as such, the license could not be changed.
