I love the code reuse possibilities of Xamarin, however there is one platform which I am concerned about: web
What is the current status of code reuse for web apps? We normally develop with Rails or Django. Ideally we would like to still use them for the visual part and just bind key parts of the program logic to C#.
So far we only have experience with Linux based servers for web apps, but Linux support does not seem like an option. I already know about Mono running C#, however I am more concerned about using Xamarin only libraries for my reusable codebase, not to mention the concurrency demands of a web apps that no mobile platform will ever have to face.
