Stretchy Tabs

We want a set of horizontal navigation tabs, preferably marked up as an unordered list, that satisfies the following:

Try 1 : ul as table-row

Try 2 : table

Navigation larger variable content one two three four larger variable five six seven

Try 3 : ul w/ image backgrounds

Try 4 : table w/ image backgrounds

Navigation larger variable content one two three four larger variable five six seven

Try 5 : ul converted to table via DOM

Fireworks source file for the tab background graphics (browser may try to open this as PNG image file, so save target as..)
