Great! :) Can't wait to see it in the main repo ;)

I also managed to make an envers module for AS7, as I already described on the forum. What you need is a:
* new module with the envers jar and following deps:
    <module name="org.hibernate"/>
    <module name="org.jboss.logging"/>
    <module name="org.dom4j"/>
    <module name="javax.api"/>
    <module name="javax.persistence.api"/>
    <module name="javax.transaction.api"/>
    <module name="org.javassist"/>
* Dependencies: org.hibernate.envers services in your META-INF

What I didn't realize before (and that's why I couldn't make it working) is that the dependencies declaration in the app's meta-inf affects the interaction between modules.

Still the bundled-envers-only-inside-app scenario doesn't work. But I'm not sure it's valid any more, as I've got it working in AS7 and you've done the integration for AS7.1. So do you still need the demo app?
