wireless midi ?

["Michael Peters" <mp@mpeters.de>]

I wonder if is possible to send signals from, say, four midi controllers wireless and without much hardware. I saw these today: http://pulsecontroller.com, and I thought it would be charming to tape a number of them to a dancer or several dancers (Laurie Anderson has done something like this years ago but I don't remember the details).
