Has anyone successfully gotten a RIR to assign anything bigger than a
/32?  I seem to recall in recent history someone tried to obtain a /31
through ARIN and got smacked down.  

Even if you're assigning a /56 to every end user, that's still on the
order of 16 million allocations.  I can't imagine anyone but the truly
behemoth access network operators being able to justify a larger
allocation with a straight face.
