I've been trying to figure out what my strategy for my first game is going to be, and I've had a couple of questions pop up considering using jumpgates to create faster trade routes. My questions are:

1. Can trade routes be set to utilize jumpgates, either automatically or manually?
2. Is their a way to use an allie's jumpgate (I doubt it, but the wiki is worded a bit oddly)?
3. If trade routes can be set to use jumpgates, is it even realistic to reach that far into the science tech tree as a trader?

Thanks in advance!
