I can't tell if you're talking about PI or ULA(-C) here -- which I suppose 
is the whole issue at hand.  ARIN doesn't/can't guarantee routability for 
any blocks, nor can it (or the IETF) guarantee non-routability.  That's up 
to individual operators.

Right, which is why we need to drop this silly ULA-C idea and just let 
everyone who needs PI get it.  Some will route their prefix publicly while 
others will not; that's not ARIN's concern.

You are aware that "small" means less than 256 hosts for a multihomed site 
or 1024 hosts for a single-homed site, right?  Everyone larger than that can 
already get a PI /48 under current policy.

If you have fewer hosts than that and have a compelling need for PI space, 
please describe your situation (including number of hosts, number of 
upstreams, and when you plan to deploy v6) so that we can discuss modifying 
policy to accomodate it.
