In order to minimize network traffic, WAP/WML is compiled
to some sort of bytecode.
WAP phones and the like only understand that bytecode,
(you don't download text to the phone, but the compiled
version) which is suitable for low bandwidth links like
cellular networks.
WML is an XML application language and it is used for
basically the same idea, rendering an user interface in the
client, while maintaining state in the server.

Right now I am researching a bit the current W3C DOM/CSS
specs,and testing the limits of current web browsers, to see
if they could possibly perform well for the task.
An example of my current test project generates:
(sorry, it's in spanish)
http://www.digipromo.com/v_desk/test_desktop.php
it's written in php and javascript, and as I become
proficient with Ruby I will be porting it to Ruby.
Please note it performs very badly in Mozilla, but it
does well on Internet Explorer >= 5.0
This test only supports 1024 x 768 resolution
and under windows  Exit = alt+f4

A SVG based client would be even better, but current
browsers aren't up to the challenge.

just some ideas...
please keep me updated if you think of something else
regarding this issue.
