[Opensim-dev] Asset Cache Sourcecode?

[Rob Nelson]

I understand.  As a viewer developer, my code would be forfeit anyway.
I already consider it a full fork due to the massive amount of changes
I'm adding to the backend, storage (I've had to create a brand new file
format for storing the voxels, and heightmap loaders are useless except
for including old terrain maps), protocol, and even terrain generation
(Minecraft's creator, Notch, provided a generous amount of help with
this).

In short, this is my Frankenstein. :)
