I might have this wrong, but it's my understanding there are three patents for this.
Deadlywind, Proteam Products, and GeForce.
GeForce had a preorder that was a complete debacle like preorders tend to be on AO.
I believe they are in Canuckistan and that may be why they didn't get a C&D from the other two
patent holders.
But it's a Mexican standoff here in the US with the other two.
So getting either company to invest more time and money to make
a product under threat of litigation is probably not going to happen.
That's why all the different AO'ers were selling the parts for DIY'ers.
