but we've all been through that for well over a decade.  we've all
been trough it and we decided that the trade-off of pain IF an isp
actually grows, and note the big 'if', is one we'll accept in the
face of routing table fragmentation and growth.

imiho, the simple and really only argument for this proposal is
that, in general, the scale of networking in africa is smaller, and
hence a longer minimum allocation prefix than in the states,
europe, and even alyc, is appropriate.
