Janine, in some ways this is already being enabled, although not specifically for engineers. Any number of traditional video game arcade boxes in bars are now networked with bars around the world and players compete not only against their real drinking buddies but their virtual drinking buddies in other states and countries.
I saw this first hand at a local bar (I was strictly on a fact-finding mission!!). And then on the Drive for Innovation I spent time with the guys at Incredible Technologies in Illinois, the makers of the famous Golden Tee arcade game, now networked.

I think we all need more information-gathering visits to our local pubs to get a much better picture of what's going on...
Who's with me??
The limiting factor in most McDonald's is battery life. Most of them have no AC outlets because of the kids, but some of them are starting to add an outlet somewhere. There is a corner booth at the local one that tends to be very popular with the laptop crowd, and there are typically two or three laptops open there.
