Ninject Rebind at runtime, can it be used as a switching function?

Firstly, my question only applies to web applications, and I try to configure most of my Ninject bindings using InRequestScope permission.

I think about ways to switch functions, and I thought I should call:

kernel.Rebind<IInterface>().To<RealImplementation>().InRequestScope();

while the website is still up and running and the switch has been clicked. If I then decide to disable this feature, I could call

kernel.Rebind<IInterface>().To<EmptyImplementation>().InRequestScope();

My thinking is that InRequestScope will protect any requested code requests, but allow new requests to get a new function.

Does anyone know from experience (or a deeper understanding of Ninject) if this can work, or if it causes more problems for me. I looked at MEF superficially, so this will be my next port of call if Ninject is not the best tool to work in this case.

One of the potential sources of the problem is that while the kernel is thread safe, you will need to click one switch, otherwise you are in a race so that everything switches as an atomic action to in-flight requests. (This is, in principle, I did not consider the code given this question).

Having said that, nothing comes to mind, which can lead to a problem.
