My comment would be that perhaps there are not many ways to skin a cat.

Yes, that is why I was asked to work on the requirements, coming from
the AAA WG.  What is needed from SIPPING is to see what needs
SIP has, and I would appreciate feedback related to this.  From the AAA
WG view point (& IESG viewpoint, I believe) is that RADIUS is not
sufficient and there are well know deficiencies with RADIUS that
make further deployment problematic.  The ongoing Diameter work is
attempting to make AAA work for the Internet, which SIP is part of.

This is very important.  This is part of the exersize with regards
to SIP - we need to make sure the real requirements of SIP are covered.

I think that solutions for SIP-AAA need not overlap, but be re-used.  If
one solution can fufill 2 requirements, that solution seems quite ideal,
IMO.  Anyhow, I think the more immediate need would be to generate some
discussion on the draft, and see what has been left out.

thanks,
John
