The protocol will deal with encrypted data, that's for sure, the data to
encrypt is a dict object type converted to a JSON string with
json.dumps(), basically, that's all the "magic" If you have something to
say about that, please let us know. Be aware, We need to change some parts
in the specifications of the protocol and translate it to English in order
to share it here if any one is curious about SpiderMonkey, but it will
take some time to be accomplished.

Thanks for the warning, but, our protocol is more than a IM Chat. We are
actually dealing with the encryption issue, and reading the Wikipedia,
looks like TLS is a very good option, we gonna study the possibility of
use it to our proposes.

Thanks for your time and help, Paul Wouters.
