AAC+ Live Encoder

We are a litle streaming provider and we need send to our costumers a live encoder to they be able to send the radio sound to our streaming server. Today they are using Flash Media Live Encoder - [login to view URL] - but it have a lot of options that we do not use, like video features. we lost a lot of time to train users remotly. What we need is a software where costumer install it, writes the name of the server, publish point, password, choose the bitrate (24, 32 or 48 kbps), choose the audio device, click connect and voala: the audio is been transmited. You make the software, I test it, the payment is made and you send me source code.
