Obviously very useful in something like GAE which needs to cold-start much more often (my crude estimate is this could save say 60% of startup time without us doing any optimisation on startup time, something I hope Stale can look at once he has worked on runtime performance). This will also be very useful in JBoss AS 7 which will offer the ability to build parts of the deployment on the domain controller before handing it off to the individual servers.

Am aiming to do it after Devoxx.

Exactly.
