No. The session talks to colord, and cups talks to colord. cups only
needs to talk to a system activated well known system bus name, and
we're assuming both colord and cups are trusted. We only assume the
session is hostile, as if you have hostile code running as uid 0 you
have bigger problems than what color comes out of the printer.

I've got a bit architecture plan on a whiteboard in my office, which
I'll be uploading either as ascii art or an svg in the near future.

DBus in the daemons is no big deal. You can't actually boot a modern
Linux distro without libdbus or a system bus installed.
