Electronic Postersessions on the way?

I saw this billboard while I was getting a tank of gas in Pennsylvania over the holidays, and it started me thinking about the direction of change in our industry.

What keeps a researcher from plugging his or her laptop into a display screen at a poster session?  How long before this becomes the way they are done?

Right now, display screens are really not portable enought to set up a poster session for a few days and then move to the next place.  But it is probably coming!  Somebody will invent a sheet of plastic you can plug into your laptop and use as a display.  You’ll roll it up and take it back to the lab, and somebody else will use it the following week.  You heard it here first.  Anybody out there who thinks they know how to do it, talk to me!
