@U0C7HNARK haven't tried. Working on getting fulcro up and running it with appengine + datastore (nodejs standard), firebase is my second option since it's a bit more expensive. Think for firebase all the magic will just be in writing you're network code somth like http://book.fulcrologic.com/#_writing_the_networking_code If you decide to give it a shot, would be really curious how it goes.
