Re: [homenet] APPSDIR review of draft-ietf-homenet-arch-10

Understand that I still haven't done my review of the document, and that 
I was the one who pushed for an APPSDIR review:

Let's be fair: The charter talks about tackling requirements in name 
resolution *and* service discovery. Once you get into those areas, but 
especially the latter, you're dealing with the needs of applications. 
Most of the work in this WG requires INT area expertise, but APP issues 
are inevitably going to pop up. I think to say that the draft shouldn't 
stray much outside of layer 3 is a bit naive. But since we're being 
fair: I've tried to keep an eye on things going on in homenet and to 
attend homenet meetings myself, and I've tried to encourage other 
applications folks to do so, and I've failed miserably on both counts. 
In large part, the former has been due to time and scheduling issues, 
and for the latter I clearly was unable to make the case to applications 
folks that this work *did* require cross-area review. What else is new 
in the IETF lately?

It sounds like we have a path forward for this document. But I've always 
been wary about INT groups doing things for applications without serious 
APP area input. (Lists of bad things available upon request.) Blame all 
around, including myself, for not making that situation better.
