In general, I like the direction Thomas is heading in... (giving
PI to the largest sites and trying not to give out small blocks simply
because someone says they need multi homing, etc...)
I would change refferances to 'end site', in favor of the term 'end
orginization' (which would imply these cant' be re-assigned to other
orginizations, but little else implyed in the meaning)
In my mind, the only real sticky point is in deciding what exactly
defines a originization as being 'large' enough to get a PI assignment.
I do think that a /40 is about the smallest sized block that I would like
to see given out as IPv6 PI space at this time. Just how you define who is
large enough to justify such a assignment I do not know.
I personaly would rather see unique street addresses be considered
as justification for space, more so then number of employees... but
perhaps either or... or some combination of both, etc...
Anyway, I do really think Thomas is on the right track with his
most recent comments and/or proposal.
