@despens @tbernard z0mg, GitHub will *not* be all that useful in a disaster IMHO.

I've worked within the field of so-called "software escrow" and what many refer to as "software preservation".

It is non-trivial to understate it.

e.g. recreating prior art to help attorneys for Fortune 25 invalidate spurious patents, while my employer invoiced them $300/hour for my time and paid me $15-$30 if I were lucky. All while contending with brittle old mostly broken code and hardware.

Grueling work.
