[ExI] Long term "5D" data storage

[Anders Sandberg]

Here is a neat little paper about storing information in 3D (+2 optical 
dimensions) in fused silica. The promising thing is that this might be 
very inert and stable, so it would make good really long term storage:

The density is nice, but it is the stability that matters.
