Interesting that Central is packaged in a Container while Aggregate is offered as a VM download.
Why not increase the utility of both by offering them BOTH in a VM that provides them as a Container package with some OS orchestration pre-set up? For the novice it would work pretty much out of the box, while for the more experienced user - they could redeploy the contained package under their own orchestration regime?
Best of both worlds while harmonising download technologies, offering community members more utility for less development effort ultimately?
Just a thought ...
