It is certainly good at maintaining confidentiality and integrity even
in this situation, because all of the data is encrypted and
integrity-checked. It is harder to maintain availability, because even
if the data *is* erasure-coded so that, say K=3 servers are required
out of N=10 servers total, you might still have too many of the
servers offline at once.

Some of the problems may be work-aroundable by using it in a different
way. I don't know but I'd love to find out.

Go for it!

I would be happy to learn the results of this experiment. People may
need to use higher expansion factors (larger N and/or smaller K), or
just to get used to their files being unavailable some of the time,
depending on the pattern of how many of their fellows's laptops are
open or closed. :-)

Thank you! :-)
