What sort of "joint approach" is involved?

My reason for asking is that the proposed I2NSF charter: 
	http://www.ietf.org/mail-archive/web/i2nsf/current/msg00245.html

contains this clear sentence:

	It is a non-goal to create new protocols or data modeling languages for I2NSF interfaces.

Obviously, I2NSF is concerned with firewalls, and punching pinholes in at least
firewalls and NATs are things that SPUD needs to be concerned about, but is
there more?

At the other extreme, the design of SPUD should not touch the I2NSF service layer,
again quoting from the I2NSF draft charter:

	The Security Service and Policy Layer is for clients to express and monitor
		security policies for their specific flows.

We should leave that sort of security to the security experts, and hope that they
leave transport to the transport experts ;-).

And if anyone from the IESG is lurking on this list, here's one more example of
why Areas matter to the structure of the IETF.

Thanks,
