Paul,

Reg your China/Chicago cluster examples.

If you plan on using multicast based discovery, note that
multicast packets don't travel natively over the Internet.

You need to work with your network/system admins - perhaps you
already have a tunnel between your sites with your own
private addressing.

thanks.  the broker's would not be dynamic and
changing, so once they're set up, it's a done deal.
ideally, i'm just using discovery to enable ease in
bringing up new brokers as is necessary.
