yeah.. I worked on something called "canary" a little while ago.

If I remember properly there were to parts.

1. A canary which would post a gpg signed message every $TIMEINTERVAL
2. A listener, which would read the canary every $TIMEINTERVAL.  If the $TIMEINTERVAL had exipred the canary was declared dead.

Not sure where the code is now.

If I can find it I'll post a link.
