They've done it on this site
http://new.ad-fontes.ch/ It's not fluid but they have coded the width to fit 1280x1024.
Not sure this is really best practice as 1024x768 users will see the site cropped and have a scrollbar at bottom.
Fluid width is not an option unfortunately due to the transparency fix for IE6 requiring some of the images to have exact sizes specified (the ones with the corners.
Still contemplating a way of coding this so that it could be fluid - it's a bit tricky because the other commonly used method for rounding corners is to use 4 little corner images inside 4 DIV's and aligh them as background images to each of the corners - unfortunately this is not a go because transparent images would combine with the main background image creating a layered transparent effect...
Will let you know if we come up with something. Rounding with Jaascript could be an option but brings about it's own set of issues...
Won't be working on this anytime to soon as I'm currently fixing up a few bugs in our current templates, 3 Column option for BlackBear and working on a new theme that is quite close to completion :)
