I hate to be a downer...but this has been all over the news and I don't get why. Bus conversions have been around for ages. From the most basic to the most space shuttle like...
It's a nice project and congratulations to Hank - I converted a van myself recently - but I fail to see the wow factor here.
Another aspect we should factor is history. Countries in Europe are in general much older than the USA. That is probably one of the biggest reasons for such rich diversity in Europe. Portugal has the same borders since 1249; Greece exists since the classical age; etc.
That is why I think that despite existing notable differences between those regions of the USA, they are on a different scale. Dialect, culture, food, general behavior, economy and (even) quality of life, of each country is affected by it's history.
Again, you force me to repeat myself. My point is that it's all about scale.
There are surely big differences between NY and Idaho, but these are smaller than those between Norway and Greece (as an example). Greece and Norway have very little in common in ANYTHING, not only "buying preferences, business opportunities, cost of living, potential market and such". They are totally different countries. The huge difference between these countries was visible more than a 1000 years ago, when Varagians guards were employed by eastern roman empire / Bizamtium. In fact, part of the reason why the differences are bigger in europe is exactly because of the longer history of the countries, but that is a whole different subject. The point is, YES, there are differences between such states in the USA. NO, they are not as huge as those between countries in Europe. (Probably, but arguably, the fact that in Europe these countries exist for way longer than the USA, is a reason why the diversity between them is so strong)
Well, DART is a far more recent project which alone can justify more activity when compared to a more stable project. Also, DART, despite being very interesting, has to be supported by the browsers and that will be hell. So, I think that's a bit too close to the bleeding edge to be useful in the enterprise environment.
And yes, if I move forward, I understand I will need real legal advice.
