DotGNU will be a complete replacement for the .NET strategy - it will not be a Free Software implementation of .NET. At the core of Microsoft's .NET is Hailstorm (recently renamed ".NET My Services"), which is in fact Microsoft's attempt to gain control of the internet and its users. In contrast, the goal of DotGNU is to give computer users full freedom to use the internet as they want. For example, the DotGNU approach to "web services" will make it possible for end users to run webservice software on their own PC, so that the users are not forced to migrate their data to the webservice servers.
也就是说,Dot GNU不是实现一个.net Framework的自由版,而是完全不依赖Hailstorm。
如果你用.net开发Web Service,要给微软付使用费。而Dot GNU的目标是你在自己的PC上就可以任意开发服务,让Internet保持开放,自由的精神。
