Maia on PHP 5.6 / Separate hosts for Front End and Back End?

Hi,

I still want to move my mail server off the current host and onto
something more modern.  Since MAIA wont work on PHP-7, I was thinking
that I'd split the services onto two machines, the modern mail server
(which hah PHP-7) and a second machine (which has PHP-5.6) to run the
front end (and nothing else).

To support this concept, I've got two questions:

1) Will Maia, as currently implemented, work on PHP-5.6?  I know it
   works on 5.5, so I would assume so -- but I'd rather not assume ;)

2) Can I split Maia onto two hosts?  I.e., can I run the php web service
   on host (a) and the perl mail processor (maiad) on host (b)?  Assume
   that the database is obviously shared and accessible to both (a) and
   (b) (and indeed is running on a third host, (c)!!)

It's been a while since I've looked at the internals so I don't recall
if there are local filesystem ties between the web service front end and
maiad, or if all interactions are via the database and cron jobs?

Is this split doable?  Has anyone else done it?  Is it a reasonable
interim solution until maia gets ported to PHP-7?

I really like the maia service and I'd rather not lose it.

Thanks,

-derek
