how to prevent ripping/recording/capturing/downloading your audio without FMS

hi
I have a question somewhat related to this, and i've been trying to get answers on some other web forums - but with no luck so far. but after seeing the above reply from "STREAM RECODER" , he looks knowledgeble enough to answer this.Anyway here's the question.

we have got simple hosting account with http only, and there aren't any streaming servers.I want put some audio files on the server, and i want to stop the users from stripping or recording them. any idea on how to accomplish this?

my current plan is to to keep the audio files encrypted on the server and then write a flash app to pull the audio file ,decrypt it internally within the flash and then play it. I am somewhat new to programming and specifically to ActionScript. would like to hear your thought on this.

thanks
