The networking stuff that uses "Games for Windows Live" does not work on Windows without Microsoft's blessing. But you can always just use the plain ol' networking stuff in the .NET Framework.

You cannot distribute XNA Game Studio (the Visual Studio bit) - this affects the Content Pipeline APIs for building content. This means, if you have a level editor for example, your users will have to manually install XNA GS.

The XNA Framework runtime, on the other hand, is redistributable.
