And hope the user reads it ? :] I suspect a long timeout would be
needed.

Unless the applications you are talking about use the embedded http
support microsoft supply. That could confuse things. Or an automated
download of pages with ie.

The technical side is not too hard. When the user first logs in, they
are added to a in-memory hash table. It would be fairly easy to set a
flag there in the request indication it was a first login (or even first
login from a given ip) and then send a internally generated page.
Ideally you'd craft an acl list that is used to test for when the page
is sent (I'd be happy to write you an acl type for the number of
requests a given user has had satisfied.).

The harder issue is as discussed above :]
