Any reason why not?

Fragility? If something goes f*ucked (physically) you lose the lot; not just one channel or so.

Then again, I could be talking from my arse.

What sort of cable lengths can MADI signals handle? I would bet that the tolerances won't allow for the types of cable lengths necessary for audio multicores at live events.

Digital multicore systems are not a direct replacement for analogue multicores. They require preamps before the A/D section and so some sort of remote control for these preamps needs to be arranged.

Most companies offering digital multicore systems have some sort of stage box system including all preamps and A/D converters which can be controlled from the other end, perhaps being controlled by a compatible digital console.

If you wanted to use MADI then you would have to build your own rack full of preamps and A/D converters as well as the necessary bits to multiplex all the channels into a MADI signal. All this has to be controlled by some sort of remote system, unless you want to be on comms all night with some stage-hand adjusting your gain pots.

I doubt you will save money compared with a complete "digital snake system". I doubt you could get anything working that was in any way use-able.

Just wondering. The digital multicore systems around tend to use coax or cat 5 for short runs and fiber for long runs. As far as I'm aware MADI is happy over coax for about 50metres, although will probably go a bit further in good conditions, and up to something crazy like 2km over fibre.

Any digital multi has the same issue of reliability. Multiple single points of failure: the cable, the multiplexer at both ends for example.

As far as I can tell any digital snake system is just a load of mic amps/converters and a multiplex cable. Of course the mic amp gain needs to be remote control.

Anyway, I'm not about to do it. Just wondered if there was anything I hadn't taken into consideration in my thoughts.

Funny you should mention that link John G.. I was with the guys from Digico the other day. Their new D1 System allows up to around 100 metres of MADI coax from stagebox to desk (remote controlled preamps). I think it will become the accepted digital standard as many professional audio manufacturers are on board with the format. See http://www.synthax.co.uk/index_comp.html and click MADI Info Centre for a good introduction to the format

MADI's been used by the likes of Sony, Neve and Euphonix (to name but a few) for years, but it was always associated with seriously high end gear, like the (in)famous ( ) 3324 or more recently the Euphonix System 5 series.

It seems to be making more of a splash in the mid - high end market now, like you mention with the RME interfaces and also the new Soundscape range. When I get properly setup I intend to go MADI with Soundscape so I can pipe it round the house more easily (and quietly!) than analogue multicore. They do a reasonably priced range of remote pres. Can't quite stretch to 1081Rs...
