ASHLAND, OR. -- December 29, 2003 -- Open Door Networks Inc. today announced that its president and founder, Alan B. Oppenheimer, will be delivering the keynote address at the MacIT (Macintosh Information Technology) conference taking place at this year's MacWorld Expo in San Francisco. The keynote talk, entitled "A History of Macintosh Networking," will also serve as the basis for a new Web site on this timely subject.

"A History of Macintosh Networking" is designed to coincide with the Mac's 20th anniversary. It draws upon Alan's 20 years experience developing Macintosh networking products, first for eleven years at Apple Computer and then for nine years at the Macintosh networking company he founded, Open Door Networks. At Apple, Alan was a co-developer of the AppleTalk network system, a co-author of the book "Inside AppleTalk" and the engineering lead for a number of key networking products, including AppleTalk Phase 2, Apple Remote Access, and the Apple Internet Router. At Open Door, Alan helped develop such pioneering products as ShareWay IP (licensed by Apple and used for Mac OS 9 TCP/IP file sharing) and the DoorStop Personal Firewall (licensed by Symantec Corporation and used as the basis for its Norton Personal Firewall for Macintosh).

"When I deliver the talk, it will have been 20 years almost to the day since the Macintosh was introduced," said Alan. "But we were already hard at work on its network months before the announcement. It was an incredibly exciting time, and the excitement has continued to this day. I look forward to being able to share some of this excitement with the community."

The talk at Moscone Center in San Francisco will kick off the MacIT conference on January 7, 2004. Alan will also be presenting two other talks on Macintosh network security at the conference. An overview of the keynote talk is available at . Following the talk, this site will be updated to include material from the talk, as well as supplemental material from Alan's and Open Door's historical archives. Open Door intends to maintain the site on an ongoing basis as a resource for the Macintosh and networking communities.
