Nope not a reality. At least anywhere I know of. Remember there is no such thing as table free design. You can replace alot of XHTML things with CSS classes but for CSS to function it needs to be called from a class call which is embedded in a table call or paragraph call etc which is XHTML. So no matter how much you bog down the css there will still need to be XHTML in the pages. I personally thing Threads has a nice balance. Threads is highly customizable rendering many many looks by editing the XHTML and CSS
