Agreed that having a configurable remote get policy makes sense.
We already have a JIRA for this[1], I'll start working on it as the performance
results are hunting me.
I'd like to have Dan's input on this as well first, as he has worked with remote
gets and I still don't know why null results are not considered valid :)

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.
