Apparently true Ghosts have been produced, just recently. I have read about people trying to do it and have been unsuccessful, a theory was that the the genetics weren't compatible. Maybe only certain lines are, who knows. TSK was successful, which is awesome. I haven't come across any others though, but thats for a different thread I guess (don't want to change the subject too much).

Its definitely on my list of things to try for .... they ARE hot!
