Actually the draft was written a couple of months ago with much emphasis 
on ISP-based solutions.  After several discussions, it has become clear 
that the same service could be effectively provided by third-parties.
We'll try make it clearer in the next version of the draft.

The main goal here is to provide an interface to help p2p applications 
in the peer selection process.  Whether such interface is implemented by 
an oracle deployed by some ISPs, or by a distributed coordinate system 
should be transparent to the standardization effort we are proposing.
