A few things
Looks to me everyone is supportive of the cause even though a few have brought up that there were Others doing similar things.
Second, just because you haven't gotten a letter from MTH doesn't mean they are not keeping and eye on the project and if it's offered to others. It has happened in the past to a member of this forum. I imagine as long as it's a personal project they'll leave you alone.
Personally I think it looks pretty dang cool. While certainly not for everyone as you pointed out.
