1) HA for master components is actually supported already, albeit with some additional work required at cluster setup. See
http://kubernetes.io/docs/admin/high-availability/ . There's some ongoing work to automate that, but it's not at the top of our priority list, based on user feedback we've received.
2) It's not clear exactly what multi-zone support you're looking for w.r.t. persistent volumes. Right now pods with attached persistent volumes are scheduled into the zone where the volume exists. There is an undesirable limitation that it's not possible to create these volumes in zones other than where the master exists, and that's something near the top of our priority list to fix soon. Is there anything else you're looking for here?
3) It's not clear to me what you're asking here. Are you referring to federating multiple Kubernetes clusters together? In 1.3 we plan to release some aspects of that (multi-cluster GUI, multi-cluster command line tools, multi-cluster services etc).
