Thank you all. I promised I'd tally today and report on this goundbreaking research project. . I ticked:

• 4 declared A's who run a lean schedule as far as number of active connected Runtimes.
• 10 B's who keep a sort of middle of the road policy
• 25 C's (including yours truly) who keep a broad palette at their hand.

This result would line up with my initial feeling that the external Runtimes feature has a more broad use than it was suggested in the conversation I referred to in the first post of this thread.

Again thank you all who participated.
