Yes and no.

Yes: I believe Dieter Maurer has implemented a flavor of MVCC for the
ZODB that ships with Zope 2.7 (although I'm not quite sure where to find
it).

No: the MVCC implementation that will ship with Zope 2.8 cannot be used
with Zope 2.7 because it depends on bits that depend on being able to
pickle new-style Python classes, which the ZODB that ships with Zope 2.7
cannot do.
