Actually, netlink comes to mind as a transport layer for something like dbus. It can not all that dbus can, but most of those so called features are actually a total wank anyway. At least it would scale. But I suppose this discussion was lost when dbus was new and it is pointless these days. Dbus will probably have a successor some day, and with any luck it will have more sane foundations... Actually, dbus is not that bad. Some of the things it can do require a approach like they took. Question is, should we have sacrificed those features on the alter of simplicity? I'm not even sure I have a answer to that...
