Okay, I think I have the picture now.  The idea of logging
in and out kind of goes out the window.  It gets replaced
by connecting, disconnecting, and migrating your online
alter ego.  So when I fire up a terminal, I'm don't announce
my presence, but instead pull the alter ego to whatever
machine I'm using at the moment.  Shutting down the
terminal would amount to pushing it back out into the
cloud.

And in cases like this, you basically remotely connect to
the "console" of your alter ego.

I think I've got a clearer picture than I had before.

That does sound cool.  The only 3G interface I've worked
with was PCMCIA and basically just looked like a modem.

I'm still inclined to think Inferno would make a good
starting point.  Suppose we have an Inferno configuration
without #U.  Now we move the whole Inferno instance
around.  Because apps don't have access to #U, state
information is pretty much confined to Styx connections
and resources managed by the Inferno kernel that gets
moved along with the running apps.  I'm sure that as
with any other approach to migration, there be dragons
there.  But as an initial line of thinking, it seems to be
a new model that's worth investigating.
