A couple of questions 
Firstly - Is there a recommended way to use namespaces in Unity? Given that the filename has to match the class name - this is a bit of a problem (I seem to remember we should create a dummy class first to match the filename, and then continue as usual)
Secondly - Since .NET DLL’s are just assemblies containing MSIL, is it possible that they can work on Mac and Mono can compile them at runtime. This would help with the first problem, if there happens to be no solution for namespaces natively within Unity.
Thanks
