Dynamic data website with 1 datacontext but multiple connection strings

Question

Is there any way to change the connection string at runtime when working with the Dynamic Data framework and LINQ.

There seems to be no way to register multiple Models (with a single shared DataContext) at runtime, I just get an exception saying the specified DataContext type has already been registered.

I have tried using multiple models each with a separately registered DataContext but it looks like it uses a dictionary internally and the key is the DataContext type name so you are limited to only 1 DataContext. Surely there must be a workaround, is there some way to reset the Http Application.

Any ideas welcome.

Many thanks,
