It has been 2 years since my former partner, mister faix, introduced me to a lighweight inline popup javascript framework. It's called iBox (try it bro! you won't regret to know this stuff!). We used it (iBox v1) for creating inline popup in our company, school management product for switching between roles. It was so easy to build the code and doesn't have conflict with other framework like prototype or jquery.
3 days ago, ibegin.com, the creator of iBox, launched iBox v2. It has more better code structure and new extended support via plugins, that will allow you to match content based on URL. In iBox v1 they had supports several document types, like images, documents and inline containers, but in v2 they have new plugin for YouTube Videos. Of course this can make our website more content-rich.
I have an idea, Google Maps plugin ? what yours ? :)
