I was suggesting a future bonobo implementation that could make use of
several back ends including the existing corba one. Therefore existing
apps would not be broken. New apps that required corba features like
network and platform transparancy would still get it if they needed it.
However a new widget that used bonobo and did not require corba could
then use an alternate (and faster) back end like D-Bus. The choice of
back-end could be left to the app.

I suggest XMl as a high level wrapper for a high level interface. If you
want to bypass the higher level and use a lower level interface like IDL
then that should be fine too.

To clarify, I am in no way suggesting anything that would break or make
incompatible existing code.
