Identical trade routes

Are there any penalties for making multiple identical trade routes, or could you just as well have 10 trade routes betheen your capital and your friendly neighbours capital?
And does anyone know what determines the average value of a trade route?

You can start a trade route wherever you like. Trading with civs counts as a plus to your relations with them. Very lucrative trading counts even more.

The value goes up the longer the route is. The value is higher when it goes to an alien planet that make more money. If it's making 26bc per turn, it'll be a better route than to a planet making 15bc/turn. You need espionage to see the revenue.

So there is actually no benefit to spreading your trade routes out? (The benefits of not spreading them out, being of course easier starbase coverage and protection.)
