> Kerkythea did a poll on their site regarding professionals vs. hobbyist

Since Kerkythea is free, that certainly helps to attract more hobbyists. If it wasn't free you would probably see different numbers in that polls.

I really like the idea of having my software easily accessible and helpful to a wide range of people, so there are a lot of aspects of free software that I like. In fact it is this same spirit of trying to be accessible that was one big motivator for me to have my price so low as it is (relative to other CAD programs).

But I just don't see how I could sustain a business with a free product, or even something in the $20 or $40 range.

To give you another perspective, I have been working on MoI for 3 1/2 years so far...
