Thanks for contributions so far...

Alternative modes of navigation are offered, the problem is in knowing which
the user would choose, and how to advise them of the variety, via the GUI.
(a sitemap is one current idiom)

If someone uses a mousewheel the page can react, why can we not query the ua
as to whether one is (not) available?

-    If the user has a mousewheel, I'd like to try offering a one armed
bandit that the user controls, by mouseover/mousewheel.
-    If the user has no mousewheel a drop down list might be appropriate, or
the keyboard could be used as a control.
-    also to provide a large sheet for some users, many of my sighted
clients would find this very intimidating, and confusing, it would be used
by say jaws/lynx, and         those not using javascript..

The problem remains that until the wheel is used, I cannot assume it is
available and serve other users well.
Can the site degrade well until we know what i/o devices are being used?
Using javascript as the guide seems rather crude, as any correlation may
make this unreliable.
Some users may prefer a map laid out, and it is unreasonable to expect them
to disable javascript every time they visit.

This example is extreme, but makes me think there must be more subtle
examples out there.
