I am greatly saddened at this news. Ralph, or rillian as I mainly knew him through the Xiph-related IRC channels, was a stalwart "nice guy", always a kind word, a moderating beacon of gentle support and help, and just someone whose presence seemed to make any place a better place. He will be greatly missed.

Seeing the other folks from Xiph commenting here, I can tell that my take on him was not unique. We lost one of the good guys, for sure.
