Hmm, that's pretty ridiculous if you ask me!
Something different about movietheatres and mobile phones: I just
read 20th century Fox made a deal with some cinemas about using bluetooth for advertisement in theatres. In the following image (which I found on some German website) you can see how the company
iSphere thinks about using bluetooth in cinemas. The idea is that at the entrance (transmitter nr. 1) you recieve the program of all the movies playing, inside the cinema you can recieve some trailers (don't ask why..), and when you leave you can get some cool wallpapers and ringtones of the movie you've just seen (nr. 3).
Besides technical issues (like sending large sized movietrailers using bluetooth) it seems like a pretty cool idea to me. Especially if there are no extra costs involved
