To be honest, I'm somewhat out of my depth in this area. Sure, I can
discuss it but you want details, and that I can't really provide.
I mentioned dbus really just as a way to encourage you to think out of
the box a little. Maybe it fits your needs, maybe not. But at least you
would have given it some thought :-)
Reading through the rest of the thread, perhaps dbus isn't suitable for
this. You have lots of messages and they don't seem to be text-based.
