Regarding Mr. Brook's letter (http://lwn.net/Articles/126572/)

As a Sun Ray administrator (and private owner) I can personally tell
you the following:
- Yes, your server infrastructure is higher; however since you are not
putting $2000 computers on everyone's desks any more, these higher
costs get recouped much faster than you realize.
- Sun Rays do very well over low bandwidth links -- I have personally
run my Sun Ray at home over a VPN link yielding less than 250Kb/s
with acceptable performance. OK, I'm not going to play a movie
or music over this link, but as a comparison a typical X application
on a Sun Ray over such a link is far more usable than the same X
application directly forwarded to a display on the same network.
Over all it is amazing how _little_ money this solution actually
requires and how well it can operate on exiting (presumably already
Since I have adopted a Sun Ray as my primary desktop at the office,
and a Sun Ray at home (connected to a local computer), I hardly ever
use my laptop any more. Sun Rays are an elegent solution to many
of computing's logistical and financial challenges.
