Hello guys, for anyone that interests, I made a small PHP script that do some kind of early merging of multiple el-v1.db. But the N900 gets unable to manipulate the resulting DB, since it isn't according to the DB itself way of use. It needs some caching (on the GroupCache for example) that I haven't done yet. Some research is needed before, including direct intervention on the DB. Have fun.
