Off the top of my head;

- inability to reuse established agreement that permits a priori
communication
- inability to work over firewalls in the long run
- inability to properly leverage the value-add of intermediaries
developed for that application protocol (such as firewalls)

It is a complete non-starter for an Internet scale architecture to do
what you and David are suggesting.  On the other hand, if you only want
Web services to work behind the firewall, then this would be the easiest
way to ensure that, because there's no pesky trust boundaries to worry
about - i.e. you can safely assume a single administrator;
