The Erlang way - dynamic upgrade of a server and UBF extensions

> I think you have missed the point in that it is NAT which is ugly.

Sure it is. As hell. But:

- reality says it's needed. Outlaw NAT and half of the people with cable
modems and *DSL routers are banned out of the net.

- with or without NAT, endpoint information (IP addresses, TCP port
numbers) ought to be in its place: as IP headers or TCP headers,
respectively. Tomorrow we will pack it into any other transport without
great problems. If we embed endpoint information *into* payload, we are
looking for trouble.

(RFC1627 meets reality)
