It's also easier to manage from a recovery POV. (No apology - pun intended!)
Easier to recover a missing frame - but a missing tile would ruin several
clients work.
I've only been using a private, local farm with home-brew UDP plumbing - but
never hit a recovery problem.
If "we" were to distibute animations across the web, say, then tile-level
message passing overheads would be horrendous. There will always be an overhead
in distributing the jobs, mainly because there doesn't appear to be any way of
cacheing/sharing the parsing results ( am I wrong?).

In this example, the individual moves were ~1-4 second scenes, each job split
into 30-100 frames. So there is an even higher level of job management - and job
recovery. Frames is good!

I understand that the render engine efficiency has been improved in > 3.7 and I
look forwards to feeling the difference.
