I like the idea of a very few of these, but I differ with some of the other CMDRs who want it to be Bubble transit only.
I think "Gate" technology could link major hubs of civilization, for now this would be Bubble<->Colonia. I envision the following constraints:
- Gates would have to be financed and built.
- Gate access would be unlocked by permit, visiting the destination the old fashioned way first would be a prerequisite.
- Gates would have a very expensive toll fee, we're talking a heavy distance-based toll. Tens of millions for Bubble to Colonia, for instance.
- All traffic through the warp tunnel, both solo and open, would route through the same instance/stream so it would be very crowded. While combat would be disabled since it's essentially a form of accelerated super cruise, collisions with other craft should be hugely damaging.
- I like the idea of falling out of the warp stream and getting stranded somewhere along the route.
