The blueprint starts out with:
When running a clustered service on Nova, typically each node needs
to find its peers. In the physical world, this is typically done
using multicast. On the cloud, we either can't or don't want to use
multicast.
So, it seems that at the root of this, you're looking for a
cloud-compatible way for instances to message each other. I really
don't see the metadata API as the appropriate place for that.
How about using Marconi here? If not, what's missing from Marconi's API
to solve your messaging use case to allow instances to discover each other?
