The issue is that by adding an Extended ORPort implementation in pyptlib
we would have to select a specific networking library (socket, Twisted,
etc.) and the transport author would be forced to use the same networking

Of course, we could bypass this by coding Extended ORPort clients in
multiple languages, or by just coding it in Twisted and letting the
transport author simply not use if she doesn't want to. For example,
goptlib has an Extended ORPort implementation using the default Go net
