I started a thread on this same topic a few months back. I was contacted by some "Aatu" Tamaskan ("regular" Tamaskan people say they distance themselves from Aatu) breeders here in the US - looking to utilize one of my males as a stud.
Later, they said someone else had agreed to let them use a male (or maybe they found a breeder willing to send a male...).
Here is the thread:
