I think Martin is right. Reading mono license, at first glance is possible
to see that everybody can use mono to develop, build and host ASP.NET
websites (WebForms or MVC) for commercial purposes.

I already developed some ASP.NET applications and run then on mono for
personal and freelance purposes.

But I'm considering buying one Xamarin license for two reasons: I want to
start to develop applications for Android, and I'm looking for a way to
retribute to the mono project. I know that contributing to Xamarin, Xamarin
people would have more resources to work on mono improve, fix bugs and so
