Of course an SMPP module for ser would be nice - but it is a lot of work
and this work is already done in kannel. So why not reuse existing software?

What if the SMSC is down or the SMPP link is down. Then you have to
reject incoming messages - or store them for later delivery. This queing
is already implemented in kannel. Furthermore you would like to multiple
SMPP links and routing rules. This is also already done in kannel.

From reading the kannel mailing lists I saw that it is not always that
easy to implement SMPP, as several SMSC have some kind of "dialect"
which requires tweaking (be liberal what you expect ...). kannel has a
long experience in acting as SMPP client. Therefore i think it is better
to reuse the SMPP functionality of kannel but find a smart way of
interacting between ser and SMPP.
