Hi Brian,

The proposed hypothetical customer needed a /24 according to their 
requirements.  A /29 falls pretty far short without some sort of 
NAT/PAT.  I suppose it's possible that dual stack would make up for 
that, but I wouldn't expect it to, currently.  Anyway, this is well into 
the realms of straw men - my current "big blocks" concern isn't a 
collo'd server, it's a hotel that needs multiple IPs per room or the 
WISP that needs a /24 and a /25.  So far, IME, IPv6 doesn't help in 
either of these cases.  I'll be very glad when it does.
