And when one unwraps all the hyperbole, ARIN is not much more than a group
of cooperating ISPs.

As for the ability to deliver -- it's being done today.  I guess one might
call that an existance proof.

Yes, allocation and routing are different functions. But they are related
functions. 

Indeed, the whole issue of address aggregation by levels of
sub-delegation, ie. CIDR, was put in place to slow the routing table
explosion that ISP's and their routers have to deal with. 

The membership of ARIN will be composed of those who have the power to
make routing happen.

I understand that making routing work is hard -- I spend a good deal of my
time working with RSVP and QoS/Policy issues related to unicast and
multicast routing.

I am merely raising the concern that one who obtains an address directly
from ARIN or delegated from ARIN via one or more levels of ISPs might
consider that the address should be an address that is, for the most part,
reachable from other parts of the net.
