Not being backward compatible is a problem. Active essays shouldnt be bound to 
its authoring image.

Pervasive Technology Labs at Indiana University has some excellent essays 
written as Squeak projects. But I couldn't get their math model ( 
http://pervasivetechnologylabs.iu.edu/lab_sda/K-12/math-model-nature.045.pr) 
project to run in my browser. This project makes use of NCLineMorph and 
GeeMail which doesnt exist in the SqueakPlugin image and I have no clue which 
version they used for their project.
