You can do this. But then it's possible that you are sending more data then
your link can handle. This is not problem, but it's possible that use some
control over the bandwidth and that your latency goes up (modem queue will be
filled).

Indeed. You can create extra classes within the the customer class so you can
give some packets a higher priority.
