I was looking for some beer to take to a BYO curry house in Great Malvern the other night, and I tried a local boozer. Not only were they happy to oblige, but they had a special Tetrapak-style carton for me to use, with a special clip for the top that kept the important liquid within.
So, proper cask-conditioned draught beer to take away. No problem. Just stick it in the box.
You can keep your fibre optics and your touch sensitive screens. This is the most important technological advance I've heard of since man invented the spoon. Cheers.
