I've created a proof-of-concept, which uses radio buttons, adjacent  
selectors, and absolute positioning to create a panel of tabs that  
works. A bug in Safari seems to prevent the selectors from noticing  
changes to the radio buttons' states. FireFox 2 doesn't work because  
I am using display:inline-box. But it works perfectly in FireFox 3  
and Opera 9.26, and initially looks correct in Safari.

Here it is, if you are interested:

("pure CSS" and functional, no JavaScript involved)

Ideally, I'd rather not have to use absolute positioning. Maybe  
someday I could use "move-to" on the content instead (if I remember  
correctly how that is supposed to work). And I had to use negative  
margins to collapse the white space; there might be a better way. Oh,  
and I'd love for "appearance" to support assigning the proper OS UI  
look, but I simulated that instead, in the second example.
