lee, you've raised a good point: web designers should consider the
future as well as the present when planning their work.

adsl will *start* to become a standard soon, but it'll take a while
to cover the whole of the uk. rural areas will not have access to
adsl or cable tv for some time yet.

besides, what about everyone who accesses the internet from work?
what about internet users at universities with slow links to
non-janet sites? there are plenty of large organisations with
overloaded internet connections that they will not, or cannot afford
to upgrade.

it's also important to bear globalisation in mind. uk companies will
increasingly benefit from being able to sell abroad. they won't sell
abroad if their sites aren't accessible over congested long-distance

of course, content replication and caching will reduce these
problems, but predominantly for the most popular sites. smaller
sites will be accessed infrequently, so their pages won't be cached.
efficient content replication and redirection is unlikely to be an
option for most sites for some time.

i think there are two issues here: sloppy coding and sloppy use of
bandwidth. cpu, memory and disk prices decrease considerably faster
than bandwidth prices. therefore, server side code (eg. cgi scripts,
asp, etc.) and client side code (flash, java, javascript, etc.) will
be able to use more resources on the client or server machines, so
long as high bandwidth connections aren't required.

i can just about remember watching a slow 486 trying to render html
including images with mosaic... :-)
