I suspect, that you're letting enthusiasm for networking overcome logic a bit.

Most people don't trust large utilities -- the electric, water, phone, cable
-- with whom they've A) lots of bad experiences B) often been miss billed
C) can track most if not all of their consumable resources

Storing your files on the net seems to run counter to the above human
psycholoical data base

In addition, the price of storage is plunging so fast (less than $100 per GB
on hard disks, less than $5 per MB on RAM today probably another 90% decline
in 5 years to $10 per GB on magnetic/optical with full read write and less
than $1 per MB in RAM including non volatile -- and not counting exotics
like hologrrqaphic storage) that a more reasonable sceanario is local
storage that you take with you and plug into what ever terminal
access/computing device you've got handy and which in turn is connected to
the network when and where possible.

Thus you can carry your critical files with you (with several back-up copies
if you want at your "fixed sites" or on the network) and with the network
providing the service that it  alone can offer -- timely, updates of
software to your fixed/hard wired locations and new mail/news/data to both
your "fixed sites" and "mobile sites".

"Fixed sites" would be those connected via some sort of wideish band pipe
--such as your home, office, in car when parked or possibly in major metro
areas, airplane seat, Amtrack seat.

"Mobile/portable sites" would be those with thin net connectivity such as
your pocket organizer when away from your notebook computer and not in a
when not wired or in a high bandwidth wireless environment (local IR or
local RF network), your notebook computer when not wired etc and your car
when way out in the sticks.

This way you can have your programs and data updated when connectivity is
available, but can take it all with you to a cave in Southern France or a
Himalayan moutain peak if you want.  You can carry with you your preferences
for music, video, firmness of your mattress from your house, your mountain
cabin to the Sheraton down the street from the Trade show.

The key missing link is the software to enable the updating to occur when
you want it and where you want it.  So that all versions of a given
document/data set are kept synchronized if yoou want them to be so kept --
including any editing to multimedia files, indexes and the like that may be
included.  In effect a much more streamlined and user friendly verion of the
MS briefcase concept.

Let's see where the Styx and Inferno technology can contribute to this
