Pathfinding?

[TheeXile]

Are there any source ports that implement pathfinding for monsters? I have a few neat ideas that would work great with that.

Pathfinding? Do you mean being able to set a monster on a predefined path and have him wander that path? If so, Zdoom can certainly do that using patrol routes. Depending on how you want the monster to act when it sees the player, you can tweak it's behaviour using Thing_Hate. eg, default behaviour is that the monster will break off its patrol when it sees the player but you can modify this using Thing_Hate.
