Again, my thinking around truly endless terrain, shifting into a newly loaded terrain would need to have the old one removed to conserve memory. In theory, using files, we should be able to construct many terrains, load them, unload them etc. I know this is far reaching however, if indeed your in a rewrite, maybe you could consider some of these idea's.

If say you have three 1024 terrains complete with hightmaps, in a truly enless world, we should be able to place these terrains in locations. in the "grid" for a lack of a better term. And where there are empty places in the grid, produce a random terrain. If my knowledge of this were hightened by a large percent, I would surely help you with this amazing task.
