Creating serializable objects from client, executing on host

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I am trying to create a system that will execute a method (in the
host environment) on an object passed to it via remoting. The object
should be created on the client side, passed MBV style to the host
where the host will execute the function defined in the interface. The
code below probably shows what I'm trying to do much better. As you
can imagine, it doesn't work; the exception thrown is shown under the
offending line of the client code.
Two questions:
1) How can I pass the objects that implement ICommandExecutable to the
host by value so that they run in the host's App Domain?
2) Is there a better way of accomplishing what I'm trying to do? Some
requirements of the problem are:
-- There could potentially be hundred's of "hosts" with the "client"
creating and pushing out commands for each of them to execute.
-- The commands may change frequently so the hosts can't know the
details of all possible commands and I cannot update or change the
host's code each time I add, edit, or remove executable commands.
Editing and changing the client is acceptable.

Any help would be greatly appreciated.
Thanks
