Hi, I will be working on the LatLng point implementation now that LUCENE-2359, LUCENE-2366, LUCENE-2367, LUCENE-1777 and LUCENE-1921 are ok.
I will propose small patches inside LUCENE-1934 but it will solve also part or total of LUCENE-2149 and LUCENE-2148. Next step after that will be to address (finally) LUCENE-1930 in current code state. Hope it helps. Nicolas
