Exchange point requests for IPv6 address space

At RIPE 39 last week the issue of IPv6 address assignments
to Internet Exchange Points was discussed.

During the RIPE meeting an Internet Exchange Point was defined 
as follows:

3 or more ASes and 3 or more separate entities attached to a 
LAN (the same infrastructure) for the purpose of peering and 
more are welcome to join.

There was consensus to assign a /64 to an isolated Exchange 
Point.  It was further suggested to assign a /48 to a group 
of inter-connected Exchange Points.  The RIPE NCC has recently
proposed to their mailing list to proceed with assignments for
Exchange Points using these guidelines. 

The ARIN region currently has a policy in place for exchange 
points that applies to IPv4.  This policy can be found under 
the heading "Micro-allocations" at
http://www.arin.net/regserv/initial-isp.html

Should ARIN consider expanding this policy to apply to IPv6?
Your feedback is requested.
