Any chance you can put all this in the D-Bus specification so other
D-Bus implementations have a chance of interoperating with libdbus-1
implementations? It really needs to be there (and I'd like it to be
there so I can add support to GDBus) - doesn't have to be super long,
just something about how to find the session bus address from a memory
segment with the name "DBusDaemonAddressInfo" or something. FWIW, I'd
be more than happy to review your spec changes.

Not to pick on you personally, but it's pretty bad that we're
releasing libdbus-1 code that relies on behavior not in the spec.
