Hey man. I'm a programmer who's done a similar thing twice, both times sticking to just Europe. I didn't go the "write a book" route but rather just programmed here and there while CouchSurfing, hosteling, seeing new places, had a couple flings with gorgeous European girls, etc.
I, also, never ran into another programmer doing this. I live in SF now (moved from the midwestern USA) and work for a startup. Let's grab a beer sometime! Or maybe I'll see you at one of the weekly CouchSurfing meetups. They're pretty big here- 50 people a week is not unusual.
