You've pointed out a serious weakness in the CC licenses. The next
version of the CC licenses, apparently, are going to have "or any
later version" in them. (Also, the copyleft ones will be compatible
with the GFDL, apparently. Like, you can take by-sa content and put it
into GFDL content, if not vice versa.)

Thanks for bringing up a king-sized bummer for me, Mav. B-) Yeah,
we're aware of this, and trying to work out a strategy so we can
upgrade to the new licenses when they come around.
