I just had a new idea.
What if we held a contest, where a WAD (or single map from a WAD) was chosen, and people had a deadline to make ZetaBot nodes for this WAD? Then, for each player's nods setup, four ZetaBots would be spawned (with coop respawn enabled) in the four player starts, and the nodes that led the bots to exit the level in the least amount of time would win.
This could encourage people to learn about bot pathing, as well as foster the ZetaBots themselves.
I will resume development on the ZetaBots. Just had to take a break. Sorry about that.
