From the IRC logs, I understand what you are talking about when
applying some things from the WMS spec, but I have one question?
It sounds to me that you can make a 2D BBOX request and you can also
specfiy the elevation (i.e. the z parameter), but does this return you
a 2D grid of the data you want or can I specify a range for the
elevation and get a 3D grid back?

Ummm.. Which WMS spec?
New WMS only allows 2D BBOX. Current (but still old) WCS allows 3D BBOX,
and has "WIDTH=", "HEIGHT=", and "DEPTH=" parameters for the GetCoverage
request.
If DEPTH= something more than 1, you should expect a 3D grid. I don't
really know what to expect if you specify DEPTH of 1 and a BBOX which
encompasses all of your vertical layers. I guess that would be kind of
like requesting WIDTH=HEIGHT=1 for the entire horizontal extent of your
coverage.
