I considered building such a site about a couple of months ago, the problem is getting the streaming results. From my research there is no public api that allows you access to results in real time at the level of granularity you would need (atleast county level). I suppose you could scrape the data off from the sites of the networks but you don't know how that's going to be formatted until election day at which point it's too late.
