Just curious, is it possible to use MCRegion with Craftbukkit? I can't seem to find any way that it will work right now (due to custom classes), but perhaps when craftbukkit is done?
Any news about that? Or even better - integrate it directly into craftbukkit. Chunk saving/loading is still pain in the ass and takes a lot of resources, so i guess that any improvement helps. On the other hand, notch have plans to release new map format. I don't know much about it, but i hope that it would be faster than current one.
