I agree with Martin here.

My "ideal" solution would be an dynamic exponential growth of the sleep time,
until we "can" send again, then calibrate to the upper bound (throughput X/sec)
by reducing the sleep time again.

What we actually want is the "ideal" X/sec. value. We should have 2 ways do get
this in the runtime state:

a) the user sets it, if he "knows" it. But this may still lead to throttling events.

b) the smsc modules itself can handle it dynamically. We can use the user
supplied value of a) as a "base" for the upper bound.

Now, this is the network flow theory part, now who is going for the
implementation part? ;)
