And we're always so fast to leap in with them, even when
we're still 200 messages behind, and not likely to catch
up before responding.

Much of this depends on the relative orders of magnitude for
X, Y, and Z.  If X is relatively small compared to Z, I don't
think many people would even have to think once before purchasing
both #3 and #1, so long as there was no contractual limitation
on what other peering could be obtained when purchasing option #3.

Assuming a reasonable transit carrier already, #2 would definitely
preclude #3.  There's greater benefit (IF you already have a good
transit carrier) in the redundancy afforded by hearing routes
from multiple sources, and having multiple outbound announcements.
If a peering session drops in #2, only that peer loses your
announcements.  Case #3, peer drops, you lose everything at that
location.  :(

Local peering points are best used for just that.  Exchange
traffic with others in your area.  I don't think LOCAL exchange
points should be used as places to try to offload traffic destined
for far-reaching endpoints multiple hops away.  That's what transit
carriers are for, and I think transit carriage of traffic out of
local regions is only going to increase, as the major players
stop seeing value at the local exchange points.  It's a great
market for a company that wants to stop selling to end-users,
and who simply wants to provide transit pipes to regional and
local exchange points.

Of course, it's past 1am, and I'm just babbling, so feel free
to totally ignore this.  :)
