Sorry, I meant to make clear that my node *is* a middleman, or what I've
been calling a relay.

And as I said in my initial email:

It would be really wasteful if nodes that are trying to make circuits
through my relay don't have any way of knowing that 90% of circuits are
going to fail (because they try to connect to an I1 node).  But maybe
thats ok, or maybe I don't understand how circuits are constructed?
