Until now I had not much interest in this stuff, but I know that some
not so smart fraudsters try to make people call their SMS numbers only
to charge them 3 times the normal price - all in cooperation with the
telecom company. 

In my case it wouldn't be fraud but a paid for service, but technically
this would be a nice option: have the telecom company charge 40c instead
of 20c per sms, and once a month or so they send me my share of the
money - no hassle with billings and payments on my side. 

But maybe this is in another league - only for the big players.

The basic idea is to recieve one SMS per day from each customer with some
data to be extracted from the message and stored and processed in the
PicoLisp app/db. Sending reply messages is optional - the feedback could
be given via a website. 

As I wrote - the optimal solution would be no costs on my side, but
rather a telecom company that charges higher prices per SMS in my name
and shares profit with me.
