asulug installfest question?

I was at the ASULUG installfest and there was a gentleman there that was trying to install Linux on a sony viao for his son who is visual impaired. We tryed to install Oralux which is based on knoppix but I was unsuccessful due to problems due to problems with knoppix and viaos. I just found a website devoted to visual impaired people and linux and would like to shoot this link to this gentleman but do not know how to contact him . The link is http://www.linux-speakup.org/ and I was wondering if anyone here knows how to get a hold of him. As I recall he posted here a few time before the install fest (ASU), and Hans was involved in this install as he is in almost all of them. Any help would be appreciated

TIA
