I have a couple minor wording changes below, but I'd support your text as-is 
if needed.

I'm content to leave that to ARIN's staff's discrection unless others 
believe that more direction is required.

         Organizations that meet the direct end site assignment criteria
         are eligible to receive a direct assignment.  The minimum size
         of the assignment is /48.  Organizations requesting a larger
         assignment or a second (or more) assignment must provide
         documentation justifying the need for additional subnets.

         Additional assignments may be made when the need for additional
         subnets is justified.  When possible, additional assignments will 
be
         made from an adjacent address block.  If an adjacent block is not
         available, organizations may request to trade their prior smaller
         assignment(s) for a single larger one, with a transition period of
         six months to renumber.

I think we also need to state somewhere that allocations under this policy 
should be from a block designated for that purpose, so that ISPs that wish 
to filter on prefix length know to use /48 as the limit for this part of the 
IPv6 space.  I don't know if we need to use a different block from 
microallocations.
