Hi Mike,

I think it would be quite stupid not to implement this protocol
directly in Smalltalk.
Implementing with use of Erlinterface will not save you any work
compared to the other solution and it will be less portable and less
efficient.

In the open source distribution of Erlang/OTP you should find a file
erts/emulator/internal_doc/erl_ext_dist.txt

which describes the protocol.
You can also look ath the Jinterface in that distribution and read the
doc and code
for the same thing written in Java.

Regards Kenneth Erlang/OTP team at Ericsson
