I have tried this out with APC, and it truly does wonders on your CPU load by _vastly_ decreasing the queries to the MySQL database. Mind it is still in a beta stage and not ready for production use, but when it is, I think it will do wonders for a lot of Joomla users with the ability to install APC, Xcache or Memserve on their server(s).

Just tried out your demo page and was amazed how smooth everything worked with the thickbox library. And showing inline content like that is just wonderful. And then it hit me: What if you could show modules in the same manner, wouldn't that be awesome?! Imagine for example if you could get rid of the more than often ugly login module on the left of the page and instead have a link to a Thickbox! I think it would be neeeeaaaaat! =)
