cm is an object, but since D-Bus objects implement multiple interfaces
we use the dictionary-style, getattr syntax to be able to specify which
D-Bus interface we are making the method call on (this syntax is also
used in Python for dictionary keys, which is a little more synonymous
with what's going on here).

This probably could be explain a little better in the book (it currently
gets one sentence):
http://people.collabora.co.uk/~danni/telepathy-book/sect.basics.language-bindings.html#sect.basics.dbus.language-bindings.python

Basically, whatever interface a method, or signal comes from, you pass
that as the key to the object.

Hope this clears things up.
