A docking component for ASP.NET MVC has been suggested before, however it is still not scheduled for implementation, so I cannot provide an exact estimate.
As for using RadDock in ASP.NET MVC, we have never integrated the control into an MVC application, but giving the fact that there is no HtmlForm, no ViewState and no page postbacks (ASP.NET page lifecycle) in the MVC website, you would be able to use only limited number of RadDock's features. Basically, the client-side functionality can be used, but in very simple scenarios.
You could try implementing a simple application using the RadDock control, and if you have any problems we will help you resolve them.
Please, keep in mind that in a more complex scenario, it might be difficult to incorporate the Ajax control into a MVC application.
