The problem with that is that 90% plus of all JS on
the net is utter crap.  The potential deployer (probably)
ends up with a fragile script that they do not understand,
and do not know how to deploy.

It is better to encourage folks over to the JS group where
they deal with scripting everyday and can spot ..
- a bad script at 50 paces,
- useability problems that arise from scripts (badly written
or otherwise)
..and also identify the pitfalls of using JS based navigation.

In the end, they are more likely to point the OP to
a robust script, even if they feel it is not an ideal
application for JS.

[ The reason I mention this is that I would like to see the
sum total of bad JS on the net drop, but I cannot see that
as likely when the authors of web pages are getting their
(scripting) advice from folks on c.l.j.programmer! ]
