Then, there are two more problems:
1. Memory consumption may be too high, as there at least are key per each
client on each device. But in reality there is a key per "path" (i.e. many
paths may be used in case of many-to-many connections)
2. You need to expire keys, to free memory. Its not only a problem to
choose default timeout, but also a potentially huge timeout queue
Note: the point 1 also makes it easy to create DoS attack.
