[Mono-list] About Mono License

[Manuel Alejandro Ceron Estrada]

Hi,

I was reading the Mono FAQ and I found this:

"The Mono runtime and the Mono C# Compiler are also available under a 
proprietary license for those who can not use the LGPL and the GPL in 
their code."

I have some questions about this:

Mono been made by many voluntary developers in addition to those of 
Novell. Are those voluntary developers agree with a proprietary license?

What if some contributor  wants to help in the Mono project, but does 
not want to see his code under a proprietary license?

There is conflict between the GPL and the propietary license?

Of course, I'm talking about the Mono parts under GPL and LGPL (the C# 
Compiler and the Runtime Library), not about the parts under MIT-X11 license

Thanks,

Manuel Alejandro Cerón Estrada.
