* - Need to rewrite GDBusAuth and rework GDBusAuthMechanism. In particular
* the mechanism VFuncs need to be able to set an error.
*
+ * - The GDBusProxy::g-properties-changed signal currently looks like this
+ *
+ * void user_function (GDBusProxy *proxy,
+ * GHashTable *changed_properties,
+ * gpointer user_data);
+ *
+ * which is problematic because some people frown upon GHashTable
+ * usage in public API (in particular some of the JS people). Maybe we
+ * need to rework it, maybe it doesn't matter since GDBusProxy is
+ * a low-level API and, for C code, we expect code generators to
+ * spit out subclasses that automatically hook up to this signal
+ * and does g_object_notify() anyway? Hmm...
+ *
* - probably want a G_DBUS_NONCE_TCP_TMPDIR environment variable
* to specify where the nonce is stored. This will allow people to use
* G_DBUS_NONCE_TCP_TMPDIR=/mnt/secure.company.server/dbus-nonce-dir
