I havent been posting lately bc I have been knee deep in theme hell. It is coming along… I spent over 3 hours the other day trying to skin the damn date picker calendar pop up, all to no avail. I finally found a way to do it. I created an alt style sheet, saved it to my style library, and copied all the date picker styles that i wrote to it and applied the alt stylesheet via the master page alt style sheet field (site/_Layouts/ChangeSiteMasterPage.aspx). It works 
One caveat: you only get one date picker style for your site collection-if you apply a different theme to a subsite, the date picker will still pick up the style from the alt stylesheet.
Hooray! Branded datepicker!!!

Oo – good idea. The only option I found was altering the file in the _layouts directory (just like you’re not supposed to…).
Hey, actually, I suspect that you’ve mentioned this on my blog, now that I check my own one!

Regarding the caveat – all the ChangeSiteMasterPage does is recurse over the site and subsites setting the AlternateCSSUrl property of the SPWeb object. If you’re not afraid of a little c# code, you could programmatically set the AlternateCSSUrl on a site-by-site basis.
Recently I’ve been looking at using a feature receiver to programmatically apply a combination of theme and master pages (for both normal sites or meeting workspaces), though it does have to be activated site-by-site. You could build setting the alternate date-picker CSS into something like that.
Actually, I might blog about both these things shortly!

Hey Andy, your idea sounds cool, the only issue for me, and I suspect a lot of folks who are designers by trade and not programmers, is we wouldn’t have a clue how to do what you suggested. I post the actual how-to’s that I have figured out for my intranet, and sometimes I really have to push my comfort level with the more technical stuff. And I suspect many designers tasked with dealing with SharePoint probably have admins that would have a coronary if we tried some more prgrammatic approaches, if we could even figure out how to do them
