Makes perfect sense to me.
Is it fair to say an ALTO server adds intelligence to the network?
hmmm, it assumes that intelligence comes from the routing layer...
looks great to me ;-)
Or is it more accurate to say that ALTO enables more intelligent
app execution via the availability of network [and perhaps other]
information?
yes, this is maybe more accurate... and I like the "perhaps other"...

That's, to me, the idea of ALTO. The apps using information about
ISP routing preferences and the network to improve peer selection.
Note that this is a very broadly applicable technique: sure,
BitTorrent and other P2P apps are most obvious users to begin with,
but any sort of app that has a choice of network destinations can
benefit. Think along the lines of CDNs, HTTP mirrors, or DNS
servers choice, for example.

Just to be sure: You envision the app selecting peers for specific

As others pointed out, an ALTO protocol is not expected to make
peer selections for the apps. On a high level, it's expected to
provide information about the network and about ISP routing
preferences.
While peer selection preferences vary from application to
application substantially, the network itself is the same, and so
the information about it remains valid.

Hi all,
I was wondering if and how IETF would address possible differences
among relevant P2P applications in the sense that different
applications may require totally different solutions. Was there any
discussion on this before on the list?
Just as an example, different criteria to drive peer selection may
work differently for give-to-get streaming and tit-for-tat BT. So
how will IETF deal with this? Standardize different solutions for
different applications? Standardize one solution for all? Pick the
most critical (heaviest traffic) applications and standardize a
solution for it?
It makes sense to clarify that at this early stage and, perhaps,
first see if the solution should and can be application agnostic or
not.
Best regards,
Zoran
