Manual Lazy load without dynamic proxy

How can I disable child collection loading?
I want to do nex thing:

Code:

<set name="Names" table="NAMES" DoNotUseLazyAndDoNotLoadThisCollection="true">
   <key column="group_id" />
   <element column="NAME" type="String" />
</set>

because lazy loading is not supported in medium trust level

And then write the following method

Code:

public IList Names
{ 
     get { 
         if (names == null) { 
             names = LoadPropertyManually("Names"); 
         } 
         return names; 
     } 
}

The main advantage of "DoNotUseLazyAndDoNotLoadThisCollection" is that I will be able to use Names collection in HQL queries

If I were to undertake this I would start looking at the bits that deal with the LazyLoading mechanism such as IProxyFactory or CastleLazyInitializer class and integrate some kind of look up on entities to intercept the lazy loading behaviour.

I think it is not a solution in my case. Dynamic proxy uses Reflection.Emit, so it can not be used in medium trust level, but CastleLazyInitializer uses DynamicProxy.
I think collection mapping should work like with proxy="false" option, but just does not load collection
