I'm interested in this, too. I have bought all available documentation, but have the same problem as you. Why is it taking so long to get an answer? I nobody using this type of client packaging yet?
My take on it is that while the JBoss folks charge for documentation they really aren't all that committed to it. After all it isn't as much fun as programming :-) It's too bad because the software is good but the doc just can't compare in quality to BEA's for example.
