Joomla "Jumi" plugin + CI potential?

[eluser]Sgt Quagmire[/eluser]
This plugin (Jumi) for Joomla! 1.5 gives developers the ability to write custom php, html, js, and even vbscript anywhere you wish on your Joomla site. The user reviews are what struck my interest the most...

Jumi seems to open up all kinds of doors for Joomla - particularly for devs that know how to program, and if the custom code could use the power of CI's framework in a stable manner, the possibilities would be endless. Of course my thoughts here could be a bit ambitious, but that's why i'm asking the pros... any ideas?
