Virtual Method Instance Interceptor
Intercepting the database connection is a head ache any day, the unity implementation of transparent proxy does not work here at all.
We want a type safe instance interception mechanism supporting the interception of calls even on the sealed classes; more like a VirtualMethodInstanceProxy
Please note that this is supported already by Linfu using the Mono.Cecil; bringing this support to unity will make it powerful enough to cater any interception requirements.

Had this done back in v2.

@Grigori Melnik: Virtual Method Interceptor is a type interceptor, but not an instance interceptor.
Hence it will not be possible to use a Virtual Method Interceptor for intercepting "SqlCommand" or "SqlConnection" as they are sealed.
Creating a Virtual Method Instance Interceptor from the base class, passing the actual instances will help in intercepting the sealed classes as well. Hope this explanation helps.

Why would not the currently available Virtual Method type interceptor suffice?

This is a really useful idea. I want to intercept ExecuteScalar/ExecuteReader/ExecuteDataset. I would like to set Context_info with my Context.User.Identity.Name, to improve my change data tracking feature

Here is the discussion I have started on the unity project hosted on codeplex.
