Actually we're not bound to the Servlet model at all. If you check the container component in SNV you'll see that it's made to be generic with a first implementation for Servlet (in component-servlet). The only constraint is that whatever your development model you must provide an implementation of the Container API, i.e. implement the notion of request, response, session and application context. This is what we'll do for example in the scheduler or XMLRPC module. To be honest, I still need to finish this container component since I don't fully know yet how the correct implementation can be passed to the component needing the Container object.
