you are right, technology is not new, but it worked for me right now.
Just tested dtmf decoder for MS Vista, reading dtmf codes from wav file.

What i need is no-GUI linux app for n900 to run it from a shell script
and invoke some action (call another script selected on a code coming as dtmf).

Look WII remote control for Vista.
