How to control the KNX bus via SMS and send notices via SMS?

[RSV4]

When using smstools I do understand that outgoing messages need be placed in a directory where they get queued, fetched and sent. So far so good. On the incoming side, messages are placed in a different directory. Here is where my question starts: I will configure the incoming path as a network path where the LM3 also has access. Is there already a scripting solution for LM3 which will periodically check the directory for new files and more important will be able to parse the file, send and read information from the KNX Bus and then will write a textfile to the outgoing folder in order to have smstools send the reply?

I am totally excited about being able to communicate with my home without having to open up my router to the outside which I do not want to do.
