See elsewhere for suggestions of how Idle might be used for such (not

Watching the Cloud9 system 'paint' on one machine/browser a moment after
I'd typed code using a second machine, brought me a childish delight
(after all the reading, learning, and fiddling of accounts and
permissions to get that far)

Disagree: there's a reason it's called the "world-wide" web!
Having said that: limiting to LAN makes life SO much easier.
(probably mentioned earlier/elsewhere)
I *HATE* using large screens, OHP panels, video projectors, etc.
Firstly, they always seem to be going wrong - the problem of too many
'moving parts'. Recently I was asked to give a user-oriented course in
DB retrieval (cf programmers using SQL). I decided to use MySQL's
Workbench, but that screen is so 'busy'. The local equipment was some
VGA or not-much-better projector. Screen text was totally unreadable!
My preference these days is to slave everyone's screen to mine, using
VNC software. It's just like a slide/movie projector and as the airlines
like to advertise: everyone has their own personal screen! (plus, can
adjust resolution, control screen enlargement, etc, to suit personal
However, a lot of training is moving away from "lectures" and certainly
"class rooms". It is becoming an async world, and even if a group
congregate into a single room, classes are organised so that each can
work at his/her own pace. So, features to join all in "lock step" may
not be so often required...
