Seconded!

Specifically, if you were looking for more to do with this, I had been
thinking about:

1. Adding this facility into [dog](https://github.com/samoht/dog) --
don't know what the status of dog is at the moment, but perhaps that
would be a reasonable thing to do (@samoht?).

2. Some form of authentication/integrity protection for messages --
[RFC5425](http://tools.ietf.org/html/rfc5425) appears to be the place
to start.

(Also, I note that this was actually one my [Pioneer
Projects](https://github.com/mirage/mirage-www/wiki/Pioneer-Projects),
which you've done without any mentoring or assistance as far as I know
-- so much for being a "beginner and non-professional programmer"! I
guess I'll mark it mostly done on that list now :)
