Had I read 2005-1 before the original post I would have suggested a
much smaller size (/44) or maybe not have posted it at all considering
the political implications. I hope nobody saw this as an attempt to
poison 2005-1 as I strongly support it even with my concerns about the
allocation size.  I really was only considering the few hundred name
server and exchange point microallocs at the time.

In any case there seems to be a strong consensus that /48's are ok for
microallocations.
