Not familiar with strace, though I've heard of it, of course. I will
have to play with this too, thanks for the tip! =)

Awesome. I have a somewhat messy test implementation that can connect
via UNIX sockets (abstract and normal) as well as TCP, handles
EXTERNAL and DBUS_COOKIE_SHA1, and can put together a message and get
a reply (only Hello tested, so far, as I haven't gotten around to
parsing the reply =)).

My next steps would be, in no real order:

* Parse and create messages without hard-coding
* Start hashing out a Rubyish API
* Refactor better into classes and modules
* Writing a good test suite =)

My goals are to:
1. connect to and query/control DBus aware applications (Rhytmbox,
notofications, what have you) in an easy and rubyish way, and
2. export objects from ruby apps in an easy and rubyish way

I'd love to collaborate on this, if you are interested.

The 1 is the length of the SIGNATURE of the VARIANT, it will always be
1, but it's correct according to the spec...
