I guess I will be trying some tracking tonight.  :)
 
I see the wobble you refer too and of course the GoPro distortion but the second shot in particular still looks pretty good to me.  I've not tried the tracking yet on GoPro but I will refer to the Mocha AE tutorial that addresses just that and see if it works on footage distorted to this degree.

Seems like you could request a sample of prior shots from the drone guy to get a sense of what shape the footage will be in?

These two examples show exactly the horrible rolling shutter wobble that David mention. You will have a horrible time stabilizing and tracking some of these, and the extreme distortion of the GoPro optic makes it a even more un-fun.

AE has a Rolling Shutter Repair effect, but i don't think it can compensate for these cases, only the usual pan shear distortion. Or? i havnt tried it myself on any of such footage actually, so i would love to be proven wrong about this.
