Where does OmniKnight fit in on a lineup?

He is not a carry, but also not a pure support, as he benefits largely from farm. How do you lane him, and what would you build on him?

Thanks for the feedback. Here's a link of an Omniknight game where he was successful as a solo long laner: http://www.twitch.tv/onemoregametv2/b/333218039?t=198m46s
