I sent Hyperdrive a note about supporting my .Mef files from my ZD . Here is the response

Dear Guy,

Thanks for your offer.
One of our customer has already sent us some Mamiya .mef raw files and we are currently working on a display support for it.
I will let you know once we have the support done.

Thanks and regards,

Customer Care

This will be really nice to have since it supports the M8, Nikon and hopefully the ZD so all my systems I can use a device like this in the field
