Thank you.  Your ability to live with proxied/NATed Internet access has
helped stave off the problems we're seeing now.  

The flip side shows up when Nintendo creates a cool new protocol for the Wii
that requires Internet access.  You Wii won't be able to participate
until you teach your proxy/NAT box about the new protocol.

I might not need a /96 for my razor, but I *do* want to have address
space that allows more than one thing in my house to participate fully
in use of the Internet.

I have a group of gear at my house that can live in a NATted
environment.  Those things get RFC-1918 space, and live happily.  I also
have a /28 for laptops, VOIP gear, etc.  -- I *like* those things
to have Internet access rather than proxy-access.

I have v6 space as well.  I'm awaiting the day that I can get it from
any common provider.
