This is super interesting to me, and I know to several other people on
this list. I only have one specific comment for now (below), but given
it is a meaty topic, I'd request fleshing out specific use cases where
GPL and BY-SA (or for that matter BY) works interact in such a way
that some form of compatibility would help. For now I'm going to dump
your email into
http://wiki.creativecommons.org/GPL_compatibility_use_cases ... if
such gets worked out enough the relevant content can be moved into the
4.0 sub-wiki.

Yes, if (a big if; per above I'm very interested, but no doubt much
vetting will be required, starting with the use cases) any
compatibility were to be enabled, it would only make sense to include
"or later", IMO. Mozilla Public License 2.0, which is about to be
final (and one of the people on this list, Luis Villa, is an authority
on), includes such a mechanism, see
(search for "or later").
