Can Zookeeper avoid NameNode SPOF for stock Hadoop?

Is it possible to integrate the NameNode and Zookeeper?  Specically, if the name node fails, can data nodes get the address of the new name node from Zookeeper?

This seems like a simple way to get rid of a point of failure in stock Hadoop.  Why don't people do this?
