>From IRC last night:

17:44 < crschmidt> There are a couple options. 1. make the left sidebar
a percentage based width, then use the rest of the page for the map.
This works in all browsers, but it means that people with Very Small
Resolutions could see a sidebar which is too small, and people wit hVery
Large Resolutions would see too much whitespace.
17:45 < crschmidt> 2. Use absolute positioning on the map div, with
'left', and 'right'. This doesn't work in IE
17:45 < crschmidt> 3. Use width: auto. This doesn't correctly work in
Safari or IE
17:45 < crschmidt> 4. Use javascript hackery. This can be made to work
in all browsers, but takes a bit more work.

This is a different case of 1 -- since we have no sidebar, we just use
100% width, and all is hunky dory.

You're thinking of TMS. WMS-C uses WMS-like requests with specific
bounding boxes. For TMS discussion, see the lists.eogeo.org tiling list,
being led by Paul Ramsey.
