I think the best thing to do with these is to back out the changes below 
and start again, I think I've got a better solution to the problem I was 
trying to solve there.

The original intent behind the changes to RemoteEvent, were to change 
it's internal handback object to a MarshalledInstance from 
MarshalledObject, so the Java CDC Personal Basis Profile could 
participate in a djinn, with some very basic simple services and as a 

Since proxy's that aren't compatible with CDC simply either won't 
unmarshall or can't be matched, this makes it relatively simple.

The problem with the RemoteEvent was that it is tied to it's serialized 
form, so what I needed was a MarshalledInstance, with MarshalledObject 
serialized form.  What happened of course is I tried to convert the form 
in the writeObject and readObject methods, however this is the wrong 
approach, since there is an Object source field in RemoteEvent that 
could too be a MarshalledObject.

Cut a long story short, what I need is a container class for 
MarshalledInstance that has MarshalledObject's serialized form, which I 
can use to replace MarshalledObject fields inside objects while 
preserving the existing object methods.  That would also mean that any 
objects that utilise it don't need to change their serialization methods.

Stay tuned.
