To expand a bit, the base system being composed that way makes a lot
of sense.  It becomes clear who's responsible for what and there's a
reliable way to recover when things go awry on the clients' sides.
Also, it pretty much *forces* you to design an interface which fits
the problem domain properly rather than exposing all the control knobs
there are without thinking how they'd be actually useful.  The
language binding issue is much easier too - it's already solved.

It seems like the only logical thing to do, well, at least to me.
Am I missing something?

Thanks.
