It's probably safe to say that we can take any Actor system and implement
it as a CSP-style system (perhaps with pi-calculus flavoured dynamics as you
have in JCSP, JCSP.net and occam-pi) -- simple, just use an AnyToOne channel,
or equivalent shared channel bundles in occam-pi. ÂHowever, the other way
around doesn't work so cleanly; Âthe Actor model is only good for problems
that fit; Âit's not a general solution to concurrent programming.
