Before diving off into real content, the name of my little π-calculus monstrosity has been chosen. As several people recommended in the comments, I'm going to go with Pica. So, today, we're going to take the dive, and start...

Before moving on, there's one question that I thought was important enough to promote up to the front page, instead of just answering it in the comments. A commenter asked about process replication, !P, wanting to know if it...
