[Server] develop .NET in different platforms

Usually, developers develop .NET in Windows Box. Now, Mono makes it possible to develop .NET in different platforms, such as Mac OS X, Unix, Linux, and of course Windows. It is good to know that I am able to develop .NET application in other than Windows platform. I do not yet have a chance to take a look of .NET. However, because of Mono Project, I may try to doing some .NET application in my leisure time. =D
