While Microsoft ASP.NET MVC is still in Beta release, it comes with a go-live license. I'm sure many enthusiastic developers and architects will create very creative ASP.NET MVC apps and run them on the Internet or intranet down the road. Luckily I came across with a twitter-like social microblogging site written in ASP.NET MVC and hosted on Windows Server 2008 and IIS 7. You can check it out at www.yonkly.com. If you see any cool ASP.NET MVC site, please drop me a note.
When you are ready to distribute an ASP.NET MVC application, make sure that you distribute your application only. If for any reason your users, customers or developers need a copy of the Microsoft ASP.NET MVC, ask them to download it directly from the Microsoft site, http://www.asp.net/mvc. This is one of the license requirements specified in the EULA.rtf document, which after installation you can find in C:\Program Files\Microsoft ASP.NET\ASP.NET MVC Beta.
