elasticsearch supports bounding box queries and even has a distance
facet. How difficult would it be to add a facet that clusters points,
e.g. like http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/examples/advanced_example.html?
Not sure…, requires some thought and investigation on how best to implement such clustering, but once the algo is in place, it should not be difficult to add it to ES.

Could use the algorithm from
http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/src/markerclusterer.js?
Here is an even simpler version: gist:1765376 · GitHub. The
clustering with this method is far from optimal, but appears to be
usable: https://www.google.com/fusiontables/DataSource?snapid=S386109S-lb.
Cool!, open an issue with the reference?

Btw, we also need a method that cluster out of clusters (the reduce phase from all the shards).

I have something like that, see Facet for clustering geo_points · Issue #1689 · elastic/elasticsearch · GitHub.
Cheers!, will be interesting to integrate it as a facet (haven't deep dived into the code). Its too late for 0.19, so 0.20 (and be part of the facet refactoring I am hoping to get to do as well).
