You could use quite cheap laptops, and the 'remote desktop' feature. You
may well find it is the simplest/cheapest way of doing it. The picture
quality will be better than any other system will manage. The big
advantage, is the much reduced amount of data needed,compared to sending
the picture...
There are DVI repeater boxes, which may approach what you need, designed
for HDTV. A search on 'wireless DVI', should find some of these.
The big question, is what you mean by 'VGA'. The original 640*480 system,
can be reproduced pretty well. 800*600, is 'do-able', with XGA, possibly
being achievable, but resolutions above this, start to need huge
bandwidths. A search for 'Avocent LongView', gets the nearest I know to a
possible solution, which is a repeater system, using the 802.11 wireless
network standard. Whether this could be used with multiple slaves, I don't
know.
Best Wishes
