There's situation where we have Laptop with wireless network card from
which we send "screen" to the wireless projector and projecting it on
the "B.I.G. screen".

Considering the fact that I don't have a clue how even that connection
works and is there any special software needed to comunicate with wifi
projector, I was wondering, is there any way to "capture" that same
signal that laptop emmites, and, therefore, grab the same picture on
the (WiFi featured)PDA for further "screenshoting"... or recording...or
