You've not been an ISP for too long.  Charging for IP space (even 
justified, not being used for spamming) is pretty common.  I don't get 
involved in sales very often, so I don't know what we charge for them, but 
I know we do.  I don't believe our rates for IPs have changed [yet] in 
anticipation of IPv4 runout.  Our standard IPv4 assignment for dedi/colo 
single servers has been /28.  For cloud, it's /32.  Anything more adds to 
the MRC.  I can see the former shrinking soon to /29 or /30 unless the 
customer demands more.
