I'm curious about the "impede the sound growth" comment. How? I don't see
the link between address space utilisation for home users and sound growth.
The sound growth of the Internet usually refers to the core infrastrucuture
of the Internet, not the edge...
In what circumstances are personal users using /29s and /30s? Dialup,
leased lines, ADSL, Cable? Hopefully your presentation can clarify this...

Is this administrative ease? One agenda item from Ruri Hiromi says "b.
Registries shall not regard administrative ease on address assignments", so
I detect a possible contradiction...?

Hopefully your presentation at APRICOT will clarify these points...
