Do i trust my implementation ? (Remoting / CAS)

Hi

Imagine that i have a factory pattern that gives me a instance of a
implementation that is not a well known. I just know the interface, and like
that, everyone can develop a implementation for that functionality.

Now, the problem.
What if I want to use something similar to linkdemand, like, i just want to
create a instance of an object if it's assembly is signed with the public
key X ? Worst.. what about if sometimes i use remoting to consume that
object in a server side activation mode ?

Imagine that i have the following code:
instance =
RemotingServices.Connect(Type.GetType(mytypefullname),myobjectUri);

Is there any way to do this ?
thanks!
