vinylshadow, I and one other person are seeking a patent; application is submitted and in process. :)
I suggest you buy them from Audio Sensibility, Anticables, or the like. If you read up on my article and follow ups, I strongly suggest initially to use quality Y cables to "build" your own prior to ordering manufactured. The home built are not as good as manufactured, but still substantially better than single. Some have mixed cables in the self-made sets. Again, disclaimer applies at this point.
If you wanted a company to work with your own selection of cable, you would have to make arrangements.
