> note, that the ping pong problem isn't an IPv6 problem as such, the same problem exists with IPv4.

Absolutely. And for an IPv4 p2p link it seems the most commonly used
solution is to use /31 on the link.

For IPv6 it seems to me we have two camps with different philosophies:

- The ping pong problem *should* be solved in IPv6, and it can be solved
if the vendors do <X>.

- The ping pong problem doesn't need to be solved in IPv6 since using
a /127 works just fine. So let's bless the /127.

Given that 

   http://tools.ietf.org/html/draft-ietf-ipngwg-p2p-pingpong-00

is from 2001, and nine years later there are still large/important
vendors that have this problem - is it likely that it *will* be solved
in the manner suggested by this draft?
