right. we're supposed to be using "a" virtual world instead of "the"
virtual world. lemme change that.

i don't know if we're supporting teleporting between radically
different virtual worlds like WoW and Second Life. But teleporting
between two virtual worlds that are both using OGP is not outside the
realm of possibility, and is a use case that has recently been brought
up in discussions about solutions like Sametime 3d and Linden's yet to
be named "behind the firewall" solution.

However... the protocol assumes the existence of a virtual world whose
different simulation regions MAY be administered by distinct
organization entities. That is, you might have one virtual world where
half the land is managed by IBM and the other half by Linden. Or, you
might have a virtual world where each region is administered by an
individual. Or, you might have a virtual world where you own all the
land. We're not defining the ownership / administration policy in
terms of who owns what, but to say "it's possible for each region and
each agent host to be owned / operated by a different
organization/individual, so don't make ANY assumptions that the peer
you're talking too is implicitly trusted."

Which is my way of saying... teleporting AND region crossings are
supposed to be covered by the protocol.

We put it in the charter in with the text: "Such virtual  worlds may
consist of  regions  administered by
distinct organizations." If the implications of that sentence aren't
clear, let's make it clearer.

do you think we should add something like "and avatars can walk across
administrative boundaries or teleport across them." ?
