I just finished a new site, it's called Design21C.
The site is Drupal based, has a number of content types and lots of theming going on, down to field a view level (I mean including creating more tpl files for parts of views).
It was a fun site to do, with lots of nuances too.
You just enter in the info you want to fill forms with, and everytime you come across a webform hit the button and it fills it in for you. Works perfectly about 30% of the time, and works very well about 50% of the time, the remaining 20% it's a little dodgy, but it doesn't add time to the form filling procedure.
