Title: Comparison

Apache OpenEJB and Apache TomEE are born from the same project and community.  They differ in two major ways, only one of them technical:

 - TomEE incorporates two additional projects; Tomcat and MyFaces
 - TomEE, as a name, more easily implies the breadth of technologies included

Effectively, TomEE is a superset of OpenEJB.  They share the same code and TomEE grew out of OpenEJB.
