Hi Lucas.
First let me say that I think your mount is incredibly innovative and truly stellar, and I hope it (and you) are very successful, because more choices and competition is great for us all.
Now, re the DDM160 from ASA, if I understand things correctly the 40A figure is the absolute maximum draw during very high speed slews only (15-25 degrees per second) and normal tracking consumption is 1-3A with a 300Kg load.
It really seems to be a professional class mount and not the kind of thing you'd find at a star party or in most backyard observatories.
Good luck with the Mesu-mount, it is a classy and exciting piece of hardware that deserves to do well.
