Yes, the Los Alamos National Lab folks' proposal: https://meta.wikimedia.org/wiki/Research:Geo-aggregation_of_Wikipedia_pageviews

We talked to them yesterday and it seems the time granularity is not as important.  That's why that dataset is *daily* and the other one is *hourly*.  Either way, these will be k-anonymized at any level.  Once we have some data up, though, I'd love for people who are good at this to try and attack the datasets in combination and from different points of view like t-closeness, etc.  I don't want to leak any info and any help on that is appreciated 'cause it's a hard problem.
