Tumbleweed's notification patent is pretty good.  I've looked at it.

Haven't you ever wondered why nobody has ever done the obvious hack to
send people a message to tell them to look for updates in an RSS feed,
rather than polling the feed?  That's why.

Absent the notifications, RSS or Atom does everything you need.  A
feed can be transmitted over https and can use passwords or client
certs to ensure that only the intended party can see it.
