IMO we should work on a configurable scheme such as:

numInitialRemoteGets (default 1)
remoteGetTimeout (default 500ms?  What's our average remote GET time anyway?)

So with this scheme, we'd:
	
	* Randomly select 'numInitialRemoteGets' from dataOwners
	* Send them the remote get
	* After remoteGetTimeout, send a remote get to the next data owner, until we run out of data owners
        * Return the first valid response.
