Zillow and Brokers Kiss and Make Up?

Prudential California steps out as debutante and launches Zillow Zestimates on its site, making it the first major brokerage to integrate Zillow’s home valuations into its site. Ever since announcing their partnership with Yahoo! (which also has an exclusive relationship with Prudential), Zillow has been on a tear spreading its API far and wide, though up until this point, mostly with other technology/Internet companies.

So does this constitute the first official industry endorsement of Zillow’s numbers? Does this mean the real estate industry is prepared to accept Zillow as the final authority on home values? I’m sure Greg over at Bloodhound Blog will have something to say about all of this.
