Yes, this is the same Barry Longyear who won the Hugo and Nebula awards for his 1979 novella "Enemy Mine." Here is his official website. His personal blog, "Life Sucks Better Clean," is dedicated to helping people recover from substance use disorder.
F. Paul Wilson, perhaps best known for his novel The Keep and his "Repairman Jack" series, has won the Prometheus Award several times. In fact, he won the first one, for this novel Wheels Within Wheels, and the presenter at the ceremony was Robert Anton Wilson.
