(That is certainly the same question I would ask -- stress on the
"simple" part.  I am a fan of simplicity.)

Unfortunately, I don't have a more simple suggestion for you.  The
ability to send messages between requests, screens, or cgi-apps is a
tough one.  In the last couple years the best system I've used has been
the architecture devised by Sam Tregar, built on Apache::Session.  It
works in essentially the exact manner you describe -- messages are
pushed into the user's session, and are then pulled out on the next
request and displayed on the top of the page.

The only improvement I can suggest is that you centralize the display of
messages in a Perl module.  For instance, you might create a CGI-App
super class and override load_tmpl() to put pending messages at the top
of the page.

TTYL,

-Jesse-
