|sure, so in the PI ranges it seems most places (save vzb?) accept to
|/48. In the other allocation sets you can get to /32 but not often
|very much further (for full reachability).

AS701 accepts and sends PI and PA /48s to Peers for about 8 months now.

Seems most (not all) folks I talk with accept PI /48s, and slightly better 
than half accpet PA /48s.  Renysis says it PA /48 reachability is much 
worse than my experience.  (See the NANOG prior to the previous)
