I agree. Exposing all these HTTP servers on the Internet is the hard part.

I contend that addition of a subsetted HTTP server on the clients to catch
INDP
notifications would be included in the client application that handles the
notication and would be a relatively small amount of code considering
everything
else the client application has to do.

There is a huge PRACTICAL difference between mailto vs. indp: indp
requires a server per user, mailto only requires a client. There is a
great difference in cost, complexity, resource consumption, and security
considerations between running a client on the Internet and deploying a
server on the Internet. Most Internet servers are used by many users, so
the cost is affordable. A server per user just won't scale to the
Internet.
