Correct, I don't believe we have any customers that only purchase space 
from us.

We got our last /19 a month or so before IANA issued the last blocks to 
the RIRs.  We have not yet used or allocated that space so we haven't 
needed to go back and don't expect that we'll be able to get more IPv4 
addresses.  We have done that in the past, but our current 
recommendation to ISPs is to be aggressive in conservation of their 
remaining IPv4 space and to be actively pursuing IPv6 transition strategies.

We have not and we don't (at this moment) see a reason to do so.  We 
really only started doing reallocation because service providers were 
changing their upstream ISP (because of price mainly) so often it was 
creating a burden on my network engineering and end user support staff 
doing the network renumbering.  We ran into this problem because these 
ISPs were almost universally using IP space allocated by their upstream 
connection provider.
