Right. One needs to define a byte-code that admits a DOM -> byte-code
translation. Then other extensions can communicate via this DOM.

That is, if this DOM is the right thing:

Similar techniques show up in the case of distributed programming, such as
CORBA. On uses an IDL (Interface Definition Language) to make it platform
independent. (And Microsoft uses COM to make it platform dependent again.)

I am not sure about the exact relation with the graphical stuff. -- Let me
know, when you have found out.

A WWW browser with links can probably be viewed as a primitive form of
distributed programming.
