Great!

I'm fine with this, but would personally rather maintain it on
pear.horde.org. It's not a problem to give commit access to whoever is
working on it, though.

Sure, that can be part of the discussion and could be a migration
path. There isn't really an API to speak of to maintain compatibility
with in exifer, anyway...

Yup. Not to mention doing the PEAR proposal, etc...
