I'm a big fan of open development, but not always open source. In open development, you release early and often and take people's feedback all the time. In open source, you expose your source which may not result in a commercially viable enterprise, and you often don't get many contributions until the project is big enough and/or the code is easy enough to get into.

I intend to make some money through minimal fees. Hey I gotta feed the wife and kids.

Is there any interest out there in open-sourcing or even licensing this? Is this different enough from Intersango etc.?
