That's precisely why I was a coward.  However, I'm not sure that N
countries is a real factor that should be considered; really, I think the
factors are a) number of segments/subnets, and b) number of ISP's
contributing a prefix to the end user.

I think the cleanest solution is finding some way to use the existing
policy but slightly amended for end-user.  Let me throw what I would
consider reasonable:  end-user networks with more than, say, 1000 segments
and 2 discrete ISP's?

On top of that, I do have one other concern...  how does an end-user
network obtain address space that would be routable when divided into the
separate geographic regions?  For example, if I want address space that I
can divide into chunks, each announced from a different Internet access
point, do I need to ask for a /32 for each of the routing points or should
the RIR's be advising ISP's that they should do filtering, if necessary,
at minimum_allocation + 4 bits, or something like that?  I realize the
RIR's don't want to guarantee routability, but they really should take it
into consideration.
