Actually I only meant those communication modes used to share
information *between* computers, and it can be shortened to non-wired
ones, such as wireless networking, bluetooth, 3G (mobile) cards and
The needed situation is for pupils using *their own* notebook computers
during tests and exams. I hoped there was a 'soft spot' in windows
common for these communication types which could be easily switched on /
off. If so, I could have a small applet running at each computer
displaying a small unique visible 'always-stay-on-top' stamp-size window
confirming that this 'communication bottleneck' was actually switched off.
