Let me be clear about what you mean here. You mean that getting through
firewalls and NATs is equally possible with SSH or BEEP (or TLS or HTTP
for that matter)?

I'd also observe in terms of charter language that the ability to
have agents and managers indifferently either side of NATs and
firewalls, and the ability to support traps in such scenarios,
are potential charter requirements. But "call home" is a solution,
and there might be others.
