No you'r not the only one in this case, we have customers with AS number and we are ambarrassed they do not announce there IP because it's icluded in our total agregate IP space, we will be very happy to obtain 2 to 4 ( \23 or \22) for each of them according to there needs, maybe RIPE should help us to find a solution about this situation.
Many small ISPs, sooner or later, want to become multi-homed and they meet with that problem. All of them usually want to run BGP even if they are assigned a small portion of address space. On the other hand, huge ISPs (e.g. Sprint) use to filter BGP announcements for prefix longer than a certain value (usually /19 or /20). Therefore, such multi-homed customers can have serious connectivity problems. The best approach for small BGP customers is to use NAT. See the slides on that at http://www.ietf.org/proceedings/98dec/slides/nat-multihome-98dec/.
