Ready for another dustup in multitouch land? Turns out that cool Displax multitouch film we saw a few days ago is actually called ViP Interactive Foil, and was developed in 2004 by a company called Visual Planet -- Displax was just showing it off to promote their new touch controller, but didn't tell anyone about the source of the film when that's where all the interest was. Naturally that's got Visual Planet in a bit of a tizzy, especially since it's developing a touch controller of its own for release down the line; the two companies have been partners in the past but there's no agreement now. Displax says it's looking at several suppliers for the film as it rolls towards that promised July ship date -- we'll see if any of this gets sorted out by then.
