User:Carnildo Greenacre/Night Skies

I'm working on customizing the night sky. Since the sky, and especially the starfield, are strictly client-side effects, this would involve storing the data in a local file. Where would be the best place to store this, and what would be the best way to access it?

Are there any plans for things like sim-wide data storage? Such a thing would make it possible to assign per-sim or per-area skies. I figure a decent starfield would require between 8k and 16k of storage; objects like comets, planets, and the like would be much smaller.
