TinyBrowser and CI integration

[eluser]Exxon[/eluser]
I am currently building a website where users can create and administrate their own websites. And I have decided to use the tinybrowser plugin for tinymce but 2 questions..

Legal is not my strong point could anyone point out if this is OK in the license of Tinybrowser and how would I integrate it with Codeigniter??? I need to be able to adjust the path for each website and limit their space according to their selected package.

Tried and failed at integration so if anyone has had any success in the past could you please help me???
