There is a connection mangement mart of mLAN that is/was not included in the
IEEE specs.
The A+M specs are available for free:

Everything but the connection management. I know thats inportant, but
I dont know how important.
Theres also the issue that some of these firewire ADDA converters might
not use mLAN or A+M. In that case things may even e easier - assuming we
can get specs from the mantufacturer.

He has partly working non-61883 audio over firewire support. I think its
quite 61883 flavoured though - so if/when its working it should be hard to
make it real 61883.
