Re. the missing functionality of DBF, would it be feasible for v.db.join to import the DBF table to a temp SQLite file, do the join and export it back to a DBF? Would the same thing be possible for other SQL ops that DBF does not support? For where=SQL module options?
It should be possible to ship SQLite with GRASS, shouldn't it -- given it's highly portable and consumes < 250K? Plus can be fully embedded w/o conflicting with system-wide installs? I suppose SpatiaLite would be an ideal exchange format for vector maps. Just some thoughts...
