Regarding MLan, maybe this is interesting information for any of you.
A bit of communication between a friend of mine and a Yamaha representative.

First of all we would like to explain about our mLAN licensing program.

What we call PTT license, which costs 200,000 initially and ? 100,000

annually as you know, provides you mLAN specificaiton. The specification

The reason why we do not open this specification to the public is the

On the other hand, audio and music data transmission protocol, which

mLAN adopts, is completely puplicly availabel specification. So, anybody

can freely write a driver for audio and music transmission protocol.

Since this requires only isochronous service on IEEE1394, this driver

We believe that writing this driver must be a good starting point.
