Hello,
recently, i worked with the cffi based port of the zeromq-library. it is
installable via quicklisp assuming that you have installed the
zeromq-library previously. it provides a socket like api for message
passing and it is quite fast. the main advantage to my mind is that it
provides support for a wide range of languages. the guide to zeromq
provides also common lisp examples which makes it easy to learn.
although it is quite low-level compared to erlang-message-passing it
could provide a basic framwork to model a similar protocol.
regards
tobias
