Sounds reasonable to me.

I'd add that if there are only two it seems reasonable that one of the 
two participants can provide the address block, when there is three or 
more that much more reasonably meets the definition of an IXP and better 
justifies allocation of addresses independent of any of the participants.

Further, the same change should be considered to for IPv6 in 6.10.1. 
Micro-allocations for Critical Infrastructure.  I think it would be a 
bad idea to have different definitions for an IXP between IPv4 and IPv6.
