+1 on a file / object storage service and on Dave's comments around client
libs. Under the 5.x model, we are developing stand alone libs for each
service, but with some level of common structure (still TBD I think - it's
basically a plugin architecture client side for passing config from the
core module to each "plugin" at startup)

On the server side storage engine side, my ask is that you look at ceph and
gluster as potential storage engines - this would help advance the 5.x
integration objectives. I know that the folks on the ops team have looked
at these in quite a bit of detail, so should have some good insights to
