We just talked about this in the last couple of weeks. This is a low-
volume list so you should just look back for that discussion for info
on confederations, if you decide to go that way...

Or, use confederations. For my applications, confederations work
better. For yours, it doesn't matter since it's a temporary setup
anyway. You may want to look into them though, just so you know what
options are available to you in the future, if you need to run a non-
mesh setup later. (Common scenarios for that include stub PoPs that
still need BGP info because clients need full routes, etc.)
