->Exchange points need the ability to petition RIRs directly for address ->space not for routability, but to ensure uniqueness.

I think exchange point infrastructure - web servers,monitoring,test traffic boxes, etc. need to be multihomed as well as globally unique.

I don't understand. An exchange point, as I think about well-known implementations, is simply a means by which to organize participants in a common place. It's an island to which multiple participants connect with the explicit goal of interconnecting to one another. Exchange point address space should only be used to establish those interconnections with the routers - not for any ancillary services the exchange point might provide that require internet connectivity. Such services should *not* be part of any exchange point address policy considered by LIR-WG, imo. /david
