I think the only "flavors" are in the Phatbox itself. DMSs (I believe) are interchangable. So, unless you're updating the firmware to your box, it doesn't matter what the original source of the DMS was.
I can take my Kenwood Keg DMS, and as long as there is no firmware update on it, I can plug it in to an Audi, Toyota, BMW, etc. phatbox.
Someone correct me if I'm wrong.
