I personally wouldn't go the path of normal maps, although for hair as short as Enkidukai fur, it's an option.
Here's my reasoning: ever looked at the Enkidukai texture layouts? If so, you'd know they are mirrored, and when you lay a normal map out in that way, one side is inverted from the other (as you can see ingame on menki plate armour, and the arms and legs and hands of any other race's plate armour). With fur, this isn't so bad, apart from the where details come in, such as around the eyes, the straps and cloth that Enkis have to cover X-rated areas.... these would invert on one side and look horrific.
What I would like to see in PlaneShift is the typical wavy hair visible in most modern games, like Fable, etc. It's not too difficult to make if your alpha renderer works right, and looks good, and is rather low poly. adding either soft-cloth physics or rigging it and manually animating it is an either option for it, though at this point PS has no physics.
And how awesome would Enki look with a mane?!
