Okay, fine. But this scenario doesn't require INDP over the IntERnet. My
point is that there is a huge pratical difference between mailto and indp
as IntERnet protocols.

You can have 1 INDP server supporting 100s of printers. In fact I suspect
this
will be a common configuration. A spooler will use INDP to get machine
readable
notifciations from the devices it is using and will then genrate email to
various interested parties - who may well have used IPP to ask for email
notification. The advantage here is the the spooler can generate
consistent,
localized messages.

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.
