I'll wait to start it because I think we should make another step and make sure that embeddedJCA could be used in our too test using @RunWith(Arquillian.class).
What do you mean by this ?
There is an example of using Arquillian in our test suite already (./embedded/src/test/java/org/jboss/jca/embedded/unit/ArquillianTestCase.java). More advanced ways of using Arquillian have been filed against Arquillian -- Aslak promised me that those would be in the Beta release.
