yes, I read the doc yesterday. seem very interesting.

The most work could be to replace pmxcs by consul kv store. I have seen some consul fuse fs implementation,
but it don't have all pmxcs features (like symlinks for example).

Zookeeper seem to be lower level.

vs

Note that for scaling, zookeeper,consul,... have some kind of master nodes for the quorum, and client nodes. (same than corosync satelitte).
I don't think it's technically possible to scale with full mesh masters nodes with lot of nodes.
