Except, if you are given bare minimums, and you are assigning out to
subtending ISPs bare minimums, those subtending ISPs will end up with
multiple networks. Some of them are BGP speakers. I can't use sparse
allocation because I was given minimum space and not the HD-Ratio
threshold space.

Wait... If you are issuing space to ISPs that are multihomed, they should
be getting their own addresses. Even if they aren't multihomed, they should
probably be getting their own addresses. Why would you be supplying them
with address space if they are an ISP?

to my knowledge, RIPE still does not issue ipv6 PI space.
so giving them their own space, is "problematic" to say the least.

ISP's get an LIR assignemnt from RIPE, no?
<http://www.ripe.net/ripe/docs/ripe-481.html#lir>
Customers could get an end-user assignment (PA space normally or PI)

   (ripe PI assignment policies)
