There's a from-scratch reimplementation of BPF in Linux (called Linux Socket Filter) by Jay Schulist in net/core/filter.c. And he appears to have worked for the _Wisconsin_ school district at the time. A Google search on "schulist filter wisconsin" reveals: Jay Schulist, a senior software engineer with Pleasanton, California's Bivio Networks says he wrote the 500 lines of code in 1997 as part of a volunteer project for the Stevens Point Area Catholic Schools in Wisconsin. "I used it for helping a local school district in my home town to connect their old Apple Macintosh machines to the Internet," he said. -- Mathematics is the supreme nostalgia of our time.
