Rich Salz has been involved with security and distributed systems for a couple of decades. He has participated in the COM/Corba war, the HTTP specifications, WSDM/WS-Management, the WS*/REST war, and others. Rather than sit on the sidelines, he is usually involved, by either writing specs or implementation. He hopes to just watch the next one from the sidelines, but it's doubtful that will happen.
He joined IBM with the acquisition of DataPower in 2005, where he is the technical lead for the XML appliance products. He has about 10 times the number of Google hits as Sam Palmisano.
