I've just been checking out the free Arri raw converter app http://www.arri.com/camera/digital_cameras/tools/arriraw_converter.html
Can ML raw video be converted in some way to utilize this. It has some nice features including realtime debayering but obviously there is specific header information in Arri raw footage that is needed to use it.
Might be worth looking at by the raw app devs
There are also a lot of downloads including datasheets to browse: http://www.arri.com/camera/digital_cameras/downloads.html and I believe there is an SDK for Arri raw
