It seems to me that geographical domains would be an awful lot easier to
implement and maintain. The uucp network is not well known for keeping maps
up to date and routing tables up to date or just about anything up to date.
A Geographical domain system would be less susceptible to falling apart if
some places decide to wait a year or two to update their tables since the
mail would be able to get reasonable close before it fails.

With a non-geographical system suppose machine a connected to site b in maine
moves to california and gets new connections downlink from a machine that
hasnt updated its tables lately. Since he has the same address his mail gets
to machine c who has no idea where to look for the address and it bounces.
with a geographical system the mail would at least get to maine or even
closer before it gets lost and there is a greater chance that a nearby
machine would know who its for. I know I'm rambling here but basically
what I'm trying to say is that a geographical system means a file will
get reasonably close to its destination before the specific machine has to be
known.

This would not hold true for internal organizational networks such as .dec
since it has its own internal routing.
