erlang/python,ruby,.. interfaces on tcp

[Roberto Ostinelli]

dear all,
 
an old question here: i'd like to interface erlang with python, ruby, and
other languages as i go. i am aware of the existance of port drivers
however:
 
. you need to develop one for each erlang / other language couple;
. a crash in the port driver brings the emulator down too.

therefore, i'm thinking to use a binary protocol over tcp/ip. this allows:

. to have only a single exit/entry point from erlang structured as a tcp
server;
. to avoid crashing the emulator if something goes wrong in the client.

since communication between erlang nodes is done by tcp, i think this could
be an interesting thing to try out.

questions:

1. do you think that this is worth a try, or you'd better really be off with
port drivers? i know there's one for ruby
http://github.com/mojombo/erlectricity/tree/master for instance.

2. what kind of fast binary protocol would you recommend?

thank you,

r.
