Hi James,

Thanks for the positive feedback :-) I found the API fairly straightforward and I don't see what could be improved. However, I've learnt about erasure code and designed the Ceph plugin abstract API mostly by studying jerasure. I'm probably biased : let hear what others have to suggest.

Cheers
