It may be worth noting that people sometimes require unique address space to
number relatively private internetworks. I believe the concept was accepted
by ARIN in policy proposal 2004-3 (Global Addresses for Private Network
Inter-Connectivity). ARIN policy section 4.3.5 now states that "When
private, non-connected networks require interconnectivity and the private IP
address numbers are ineffective, globally unique addresses may be requested
and used to provide this interconnectivity."

If a /29 works in this sort of situation it seems reasonable to allow such
an assignment, rather than forcing a /24 on the network and wasting 248
addresses. You *might* see announcements for /29s but I expect that very few
of these small PI assignments are intended to be publicly routed.
