Using TypeMock with NUnitAsp

Most of my work with .NET involves writing custom ASP.NET controls. I use NUnitAsp to unit test the controls. I have a requirement for any mock object framework that I have not been able to find in other products, I'll try to explain it below and maybe someone from the team can comment.

My unit tests run in the NUnit process, they effectively use the NUnitAsp code to make calls to a test aspx pages that contain one of my asp.net custom controls. The test aspx page is designed to allow me to drive all of the features of the asp.net custom control. The big thing I am missing in my scenario is the ability to use a mock object framework within my unit test code (setting up expectations, verifying calls etc.) as my unit test code is in one process and my asp.net custom controls are running in the asp.net process.

As an example, lets say I have a custom control called AccountDataDropDown. The AccountDataDropDown control uses an instance of the IDataAccessLayer interface to retrieve a list of accounts from the database and then populates a standard Html select tag.

I'd like to be able to mock the instance of the IDataAccessLayer interface, setup the expectations in the unit test code and then have the AccountDataDropDown control use the mocked instance.

In the past I've manually achieved this by creating a primitive hand coded mock object that stores all of its state data (by state data I mean the expectations that have been recorded) in a file, the unit test code and the asp.net code create instances of a IDataAccessLayer class which uses the file to "share" the state data between processes.

Is there any feature of TypeMock that would help me out.

Thanks
