Tony,

Note that I did say we should buy no more than 1.  If it doesn't work,
it will probably be a half hour set back for someone, and then I assume
they will move back to a normal projector.  I do expect to get work
done!

Mat -

There are obviously two laudable goals here:

1) Getting work done in meetings; and
2) Testing out the technology that we develop in real working
environments.

Unfortunately, it is not clear to me that these goals are not in
conflict.

Putting it another way, I think it is a great idea for you to guinea-pig

these new devices in your meetings ;-)

Regards,
Tony
