I worked on McCormack & Dodge's accounting system and that was open source. That was debugged with and through user feed-back.

For the government, I worked on other app.s which were open source. Actually, the concept of 'closed source' does not apply in government work except for classified stuff.

Before Bill came along, you had a hard time trying to sell closed source in the software business. Actually, you still do. There is NO WAY someone is going to plunk down a million dollars for software without the source.

That's why Microsoft is getting into games, trying to lock in users beyond its desktop with software patents, and so on.

It sees the end of closed source.
