I see what you are saying here. The idea is analogous to cells in a body
(with common genes) not being in conflict. Cells in a body sometimes do go
wild (cancer) but with good error correcting codes whatever is at the core
of an AI could copy to end of the universe without making an error.
It seems to me that the core would have to be absolutely impervious to
outside influences--which is in conflict with intelligence--to the extent
that intelligence has to do with learning. Otherwise units at the ends of
communication delays would diverge. I suppose every AI could be
broadcasting its total information stream into memory and receiving the
memory dumps from every other AI. It would have to treat the experience
(memory) of other AIs with equal weight to its own. That would keep at
least close ones in sync, but if there are growing numbers of these things,
the storage problem will get out of hand no matter what media is being
used. (In fact, it might make the case for very few AIs. Even on per star
would get out of hand.)
The problems this creates are bad enough that far apart AI cores would be
forced to consider themselves as different "individuals" just by weight of
different (unsync'ed) post creation experiences. I think this is true even
if closer ones engaged in total mind melding.
I like the idea that AIs could avoid having conflicts of interests in more
ways than humans can. People would probably fight a lot less if they
walked away from every meeting not knowing which one they were.
I am sure you will point out flaws in the above reasoning. Please do, it
is an interesting topic.

With FTL there doesn't seem to be an obvious limit. Without . . .
eventually your brain undergoes a gravitational singularity.
