What is this leak?

Just dove by my parking spot and noticed some shady-looking puddles! Something is leaking from the ZHP .

Looks like oil, but doesn't feel like oil. Ran my finger through it numerous times - not oily at all. Seems to be dripping near the rear axle.

Checked the oil, and it's above the minimum mark.

Any ideas?

Could this be the diff leaking?

I did have a look under my car and everything that I could see was dry. Interestingly enough, the lighter-coloured liquid seems to be spread over a good couple feet, perpendicular to the stall's direction; my parking doesn't vary that much... going to call up my mechanic right now and see if I can drop in for him to have a look.

Could be Trans fluid, power steering fluid or the fluid inside the front control arm bushing.
