You could add two GTileLayerOverlays on top of each other. One GTileLayerOverlay has the left tiles, and the rest are blank, (transparent), tiles, and the other GTileLayerOverlay has the right tiles, and the rest are blank tiles.
Then on your script, you can do map.getBounds() and split it in two, and based on that you can decide which tiles to serve to each GTileLayerOverlay. You might want to add a random parameter to the tileUrl in order to prevent caching of the tiles. The problem you might have is that the center longitude of the map will (most likely) not coincide with the edge of a tile, so the split would not be exactly half-half. Another alternative might be to use two synchronized maps next to each other: http://maps.forum.nu/gm_maps_in_sync2.html -- Marcelo - http://maps.forum.nu -- 1.
