I see the value here but I have a few problems with the current state.

To begin with, I find the "cost" name overly confusing. I realize the 
draft already says this is not necessarily real cost but it still leaves 
people with the wrong impression (and I've confirmed this in 
conversations these days). So let's just go for bias or something (I 
also like fondness).

The draft is not currently very explicit about exactly how this works in 
the selection of candidates but I assume it basically means: "if it's 
all the same to you, I'd much rather you get in touch with me here than 
there."

The trickiest part here is how to assign importance to this new bias as 
opposed to existing metrics such as RTT for example. We could say it's 
up to implementations or try to come up with some recommendation for a 
formula.

The other thing is that I cannot at all see the value of the network ID. 
Why is this necessary?
