Yeah, been kicking this around for a while - I think it's possible to
drive this sort of thing using a service compositing approach and
probably a single event handler in the client (there are other ways to
get the information to the client which may be more appropriate for
"expert" users).

So, the client has to know a little bit about what's going on but you
can confine it neatly to one place which makes thread management etc
simpler.
