It's is definitely interesting when I read everyone's post. When I lived in the Philippines, there were cattle ranchers who would "park" their carts in the middle of our land selling leather materials, and that was without technology. It was their way of making a living and perhaps also because they can carry everything with them. So all I can say is, it is definitely something to try and invest in. I also remembered one important thing, if you plan to do this yourself, it will take lots of time and even more so than a full time job. If you then decide to have a business partner, make sure this person is someone reliable and willing to handle whatever comes along with the business etc, meeting with other vendors with you. I had invested on an art bus, a bus that would travel city to city teaching children how to paint or make art. One day my business partner didn't go with me in dealing with our marketing video guy (who helped us with visual material) and to make the long story short, it was a bad idea to go by myself, hence the unreliable business partner who didn't commit in going with me. These are just my experiences and hopefully this will give you a sense of what to expect perhaps.
