issue 19 -- same addresses for both directions?

It looks to me that the decision on issue 20 (who decides)
is the main determining factor issue 19 as well. If issue
20 resolution is that the initiator decides, then it more
or less follows that we have same addresses in both
directions. We can imagine different addresses even in
this case, but it does not appear to be very useful or
necessary.

On the other hand, if we decide in 20 that the decisions
are independent, then it may in fact be very hard to
ensure that the two directions use the same addresses.
As a result, allowing different addresses would make
more sense in this scenario.

My conclusion is that we should focus on trying to
solve issue 20 first.
