We're a bit thin on documentation, so you'll have to do some digging.
But it shouldn't be that difficult. ;-)
We already support asynchronous deployment -- see ControllerMode.ASYNCH.
There is also already a simple way to declare top level deployment and service dependency:
* see jboss-dependency.xml at http://community.jboss.org/wiki/JBoss5custommetadatafiles
But since you have services running in diff VMs, you could implement your own DependencyItem,
which would use remote call to check if dependecies are satisfied.
ps: there is remote support on our roadmap, but it's far away atm,
so, if you produce some interesting/nice solution, we could make it part of Kernel ;-)
