Just a few points, about current situation in
hardware performance trends, and why this
will eventually get to be everybodys, and not
just people from the edge problem.

1. Pure processor power improvements by increasing
clock sppeds are definitely slowing down, since limits
imposed by laws of physics are near to this principle.
(I saw principle, not technology. It is not like we are waiting
some new technology to produce 1000 times faster and
smaller transistors, it will never happen, since it is not possible).

2. On the other hand, optical communication techonology
is growing like mad, and there are no laws of physics to
make it stop in sight. We can expect 1eX times faster
networks in future.

In some future you can expect processing power to
be limiting factor in your online experience, and not
bandwidth of your link like it is today.

Only possible path to take will be all kinds of parallelism.
Multiple data single instruction (MMX SIMD),
multiple registers with multiple widht (our bellowed 64 bit:),
multiple cores in one processor,
multiple processors in one computer,
multiple computers in one cluster,
multiple clusters at one task.

Some of them can be utilized for better performance
by processor itself, some by operationg system, some
by application server, some by framerowk libraries,
and some by carefull programming on your own.

But first two needs compiler support to work at all.
