Google + Keyhole = Advanced Adwords Geo Targeting?

Thread Title:
Why Google Bought Keyhole
Thread Description:

What if Google could overlay Claritas PRIZM segments against users IP addresses – and allow advertisers to adjust their bids up if certain households searched on specific terms? For example, if a search user was identified to be in the “Landed Gentry” segment, the advertiser may be more willing to pay more for this person’s attention
