Good god people. Advanced jump gates are NOT unfeasable.
Yes having them from one capital system to another is a bad idea at this current time as the trading dynamics would be terribly upset.
However, other uses of them are not out of the question right now.
Think of it this way.
There's a system surronded by darkmatter clouds that has unstable jumpholes appearing every so often in it (Not in game, just how this would make sense. Jumpholes are natural and they have been known to collapse etc from ingame lore).
BMM say send a probe through one of these jumpholes. The information it sends back shows the system to be full of minerals that would be a huge asset to the company. Unfortunately the hole collapses soon after.
Now, using those jumpholes would be far too risky and unreliable, who knows when a hole could collapse and another not appear for a long time? Plus they are just plain dangerous apparantly.
So to get around this, they try to build a gate that can bypass these Dark Matter clouds.
Essentially, an advanced jump gate.
It would look different and be different from the others in it's animation etc but it would operate the same.
The reason why we don't use advanced jumpgates for long distances is simply because we can see how systems can be close together and require a gate or be far far apart (Tau systems) and still use the same type of gate.
Distance isn't really an excuse for such a gate.
However, dark matter avoidance and other things are.
