I'd read it before, but I did not understand certain unstated assumptions.

I've glanced through it again.

This seems to solve a non-problem, that is, how PI addresses are handled
inside an ISP or between its peers.

The real problem this does not seem to take a stance on is (but there is
some text in section 10, not sure if related), who is advertising the PI
routes to the default free zone (or upstreams, in any case)?  If these are
not aggregates, would explode.  If these are aggregates, the upstream and
the ISP will have handle traffic that does not belong to it, because by
the definition of geoPI addressing, it is not completely aggregatable --
else it would not be useful at all for multihoming etc. purposes.

I guess the goal(s) of the draft should be stated as clearly as possible,
in the abstract or the introduction section.
