This seems a big drawback to the standard IP number method.  Think about a
network sharing an IGP containing thousands of dialup ports.  That's where
I am.  How many dialup ports can you have before one SMTP gateway just
doesn't cut it?  Sure you can play games with load balancing, layer 4
switches, or perhaps route filtering but why force money or effort to be
wasted on such things?
