Yes, but distributing stuff using repligard is going to be difficult.
Two-phase commits are notoriously hard to get right.

Yes, but some queries do something like

SELECT page.id,person.lastname FROM page,person
WHERE page.id=5 AND page.author=person.id

which is simply not going to work when this data lives in a different
store. I'm not saying "don't do thid", but rather "mind the pitfalls".
