Possibly Tom Coates?
Either way, the person I am doing a laughably poor job of describing was at the FireEagle event but I definitely remember him being a peer/coworker of Tom's - he wasn't the center of attention that day.
Sigh.
"So I want to personally thank Seth Fitzsimmons, Samantha Tripodi, Jeannie Yang, Chris Martin, Ben Ward, Kevin Ryan, Phil Pearson, Rabble, Arnab Nandi, Simon King, Mor Naaman, Ayman Shamma and everyone else who worked on Fire Eagle at any point in its life. I learned an enormous amount from all of you."
