Yes, it's in the plan.
Do you can precise version when this features will exists?
It can be very usefull in optimalisation....
I don't know if we have a timetable for this feature just yet. However, if you look at the action chaining/pipeline concept, those are all "in VM" and can solve a lot of the "in VM" use cases.
It won't be available in the 4.2.1 GA release.
