My wet dream is that one should always start by developing a reference
implementation of any given protocol in Erlang. Then -- only if performance
is not good enough -- implement (or buy) one in C. The Erlang-based
implementation will help you understand the protocol fully, can serve
as an education and testing tool, and should eventually (this should be
a goal for the development of Erlang) be the preferred implementation
to use in your commercial product.
