Map updates

Is there a way to just update a map without re-rendering the whole thing?

For example, if I just upload an archive with the level.dat and only the regions that have changed since the last render?

I have a large (700+MB) server map that I would like to update every few days, but my internet upload speed is only 896kb, so it takes over 2 hours to upload the whole map.

If it's not possible, could this be a feature request?

Interesting concept.

I just got back from vacation and have a bunch of stuff to catch up on but should be able to throw together a solution for this fairly quickly.

Look for more on this next week.

It has been a month, and I haven't seen anything yet. Am I looking in the wrong place?

You're not missing anything.

I under-estimated the project work that I had on the horizon when I replied while on vacation. I'm getting caught up on the other projects and will look at this as soon as I have time.
