I'm not a fan of copyright assignment, and would like to find (if
possible) a solution that gives you what you need without requiring
it.  Requiring copyright assignment allows you to "pull an Oracle."  I
mean no offense by that and I hope you understand my intent in saying

Would it be possible to have, instead, a contributor agreement that
allows contributors to retain copyright while at the same time
granting you a non-transferable, non-revokable, exclusive right to
relicense their contribution under the ASF2.0 license at a time of
your choosing?  This allows contributors to "know what they're getting
into."  It allows you to transition smoothly from GPLv3 to ASF2.0 when
you feel the "time is right," while allowing contributors the comfort
of retaining copyright to their code, knowing that they will not later
face all their work being swallowed up as in, for example,

This grant to you would be non-revokable (for your comfort) and
non-transferrable (for the contributor's comfort).  It would be
exclusive to you as an agreement between you and the person submitting
code to you.  Is this sort of thing even workable?  I'd be interested
in the opinions d-l at large, as well.
