I'd vote for keeping it on the server. Before it was done server-side the lowzoom tiles always seemed to be a bit of a mess with inconsistent styles and frequent Unknown Type tiles.
Compared to the old lowzoom scripts the [EMAIL PROTECTED] integration has lots of differences. So currently there is no way "unknown tiles" or something like that can happen.
Essentially it does download every tile from server, except caption tiles which are generated directly when caption layer is requested as well.
3 differences:a) When server tile is plain land or water, the corresponding information from oceantiles.dat is used. In case of a conflict a warning is issued as well. b) black tiles and plain mixed tiles are replaced by oceantiles.dat information and also warned. Black tiles should not exist anymore, bur are treated like the mixed marking 1 pixel tiles as well. c) Tiles which are empty land/sea/mixed and marked mixed in oceantiles.dat are output as dark blue tiles to encourage fixing of the error.
In case there are warnings and no local modification to oceantiles.dat have been done, something is wrong and should be fixed either in oceantiles.dat or in the data (e.g. sometimes broken coastlines lead to full white tiles).
A last note: Enabling fork option greatly speeds up the stitching, as downloading is done in parallel then :-)
