I was looking at /tmp/lll, is that just a log, or do the events get sent there, then another process acts on that information to popup the SMS received and whatnot (or call, or whatever event)?

If the latter, is there a way to hook the write, to allow/disallow being written to the file?

How would you suggest an interruption for incoming SMS?

EDIT::
Scrap that, dbus-monitor --system outputs, but how do I interrupt it, before it happens?
