I guess if all tasks have subscribers, this could be true...  Even in
Job, not all tasks have subscribers although I admit that if you are using
it with PAM so each login starts a new job...  most would.

I tried to send what I had so far twice yesterday but the list server is
eating it for some reason.  Someone is going to check in to the list
server configuration today.

I'll respond to more of your post later.
