[Tm-rid] RAA/HDA - drawing the line in 32 bits

[Robert Moskowitz <[e-mail]>]

In draft-moskowitz-hip-hierarchical-hit-01.txt, I use 14 bits (16,384) 
for the RAA space and 18 bits (262,144) for HDA within each RAA.  Seems 
reasonable enough for me.  Good as any guess about the future.

Tero Kivinen suggested a soft separation with the HDA in little endian 
order.  This way we might have time to figure out where we need more, 
RAAs or HDAs.

Sounds interesting, but I see potential problem(s) if one RAA really 
runs up its number of HDAs and thus limits the number of RAAs in total 
as a result.

Oh, and the 32bit space will be represented in DNS as nibbles.
