That's great.  You and I are in a similar situation.  I know a limited 
amount about capabilities and even less about how to implement a 
language to support them.  That is why we are here on this list.  In my 
understanding, the basic premise is that you can only send a message to 
a reference you have.  You can get references only a few ways.  Someone 
basically has to give you the reference to an object.  The language and 
environment should be secure from leaking references.

I would recommend reading as much as possible on the erights site.  It 
is very interesting.
