I personally think 'disaster market' is a terrible way to refer to people in need. I realize that business is business, but they could also release it as open-source, or set up something like the Raspberry Pi non-profit. Some people do want to help the world, even if there's little to no money available.

It still costs money to design and build this equipment, sadly. "Helping the world" can't feed your family. =/

Raspberry Pi non-profit is awesome - but they made a very low cost, very versatile product. This is so unlike disaster equipment as to be impossible to their firm design.
