This is what I thought. Even if it did work the way I was sort of
outlining, I wouldn't want to have an extra latency delay as the
internal server handed data off to an external server wasting a cycle.

I copied Rui on the first message thinking that this would be the
simplest solution. I'm not sure what the right answer is. Maybe there
are some internal connections you want to see, but I think most you
don't want. Maybe some button to display/hide connections from an app
to itself would give people the most flexibility.
Hope you're having a nice Sunday,
