[HamWAN PSDR] Do we have any cloud / distributed storage experts?

[Eric Wolak]

Hey Bart, 

I'm new here, but I figure now's as good a chance as any to contribute.
I have quite a bit of experience with distributed systems, and I'd love
to help. Let's talk reconciliation semantics!

I'm wondering if anyone in the group has knowledge to provide some design feedback in distributed storage systems.  Not from a "how to use it in AWS" perspective, but rather how to design them ground-up.
