Have you ever seen those photo frames that display on electronic image? They are almost like a small video screen, where one can change the picture at will. I've even seen some of the newer ones where you can change the picture remotely.
You could set one up at Grandma's house in Pittsburg, and change the picture displayed from Seattle.
That got me thinking.
A network of sorts of brewpubs could take pictures of the chalkboard tap list, and upload the image on a real time basis. Then, on the wall in each brewpub would be a few of these framed screens to show what's on tap at other brewpubs around town. You could be having a beer at my brewery, but know the guy down the street just tapped his famous IPA.
(or having a beer at that brewery, and know I just tapped my Amber.)
I think it would show the beer drinking public, that all us brewers are friends, and want to help each other.
