What issues are you having with JMS? Seems to me that JMS with a constrained MDB (i.e. container can not make more than, say, 5 instances) would work well at letting you control resource uses. And this doesn't sound like a particularly exotic use of JMS.
So I'm curious what problems you're encountering with it.
