Here's an interesting piece on Heathrow Airport's future; the premise is that a two-runway airport isn't going to be sustainable as a hub and that they need to expand. I don't know the logistics there, but many airports have sufficient NIMBY issues where expansion is problematic, especially when the city grows up around the airport.
One interesting aspect of reading the Telegraph piece was that I had banner ads plugging a local Michigan college. Read globally, get ads locally.
Or at least localized. Some of the cheesy ads are in [insert city here] format. The ad that was running for the Lexington mom earning beaucoup bucks only looks like a dead ringer for the Midland mom doing the same thing.
One interesting way around visa rules; have the office space in international waters. Thus, workers can get a visitor visa and commute out to the office ship moored 12 miles off SanFran. They're not working in the US, just living there, and a tourist visa is easier to get than a green card or H1 tech-worker visa.
Getting broadband out to the ship is the big trick; a long extention cord might be an option in the form of an underwater cable out to the ship's locale.
