Does anyone know of a good solution for broadcasting a powerpoint from a
desktop to a remote monitor wirelessly? I am looking at setting up some
digital displays at a retail operation and would like to stream the
presentation output to several monitors simultaneously. I am not looking for
extreme ranges, but will need at least 100 metres or so. It would have to
include the audio as well.

There are many video to monitor solutions out there, but the output from a
box is not compatable with the systems I have found. I want to avoid putting
the presentation on dvd if I can. Putting it on dvd and then streaming it
using a standard wireless video transceiver would be fine, but I want the
user to be able to make simple changes on site, more complicated changes
would be done by me remotely.
