Well, cool idea. Has been the last ten years or so. Not many products use it.
Presonus dit put out a product called Firestation using mLan, and a lot of people seems to have had a lot (and I mean a lot) of problem with the mLan part of that box. This is only the actual implementation in that case, the idea may still be very sound (which I do believe). But I guess most of us are not buying ideas but trying to get things that actually work.
So, as far as I am concerned I have no hurry buying my first mLan product. If I had one already, it might be different. The idea of connecting things virtually on the mLan bus is really nice.
