That is freaking genius.
If you go to a bicycle shop, they'll have a replacement cable housing that they can cut to length, used for bike brakes. The good ones have a teflon liner sleeve. That makes things much smoother.
It still doesn't hurt to spray a lube inside though, and lube the cable first, just for corrosion protection.
