issue 1 - indirect indicators

It seems to me that our understanding of this problem
has develop a lot since we originally wrote issue 1. We
now have a better understanding of what other components
there are in a system and how Mobike interacts with them;
we are debating which entity makes decisions (20), we
have decided what to do when the sign of trouble is
a lack of packets (16), we have decided what kind of
connectivity assumptions we make (17), and we are
working through how the appearance of NATs on a
new path affects MOBIKE (3).

In conclusion it seems that we are already covering the
details in several other issues. Therefore issue 1 will
be closed as a duplicate.
