Hmmm. Vocabulary overlap again. My flippant suggestion for a library name
came from SDL where "signals" are the objects sent/received by FSMs (should
stick to the vocab I suggested myself ;-(.

Anyhow. As far as what it would do? I was trying to fill in the next piece
of
the puzzle. You (correctly, of course ;-) separated your FSM library from
anything to do
with "comms". If I was to apply your library to implementing some
distributed, telephony
FSMs then I would have a bit of work to do. From the point where an event is
generated until it is presented to a FSM, there may be some mountains and
rivers
to cross (i.e. a network). This is the area that I was alluding to with my
mis-named
boost::signaling.

Of course there are a bunch of applicable technologies, but that is all
tangential.
As far as boost::fsm is concerned this stuff is only interesting in that it
helps clarify
the scope of your work (to me ;-) and how it might mesh with the next piece.

Thanks,
Scott
