Nanomsg creator Martin Sustrik has a new blog post out this week about some discussions happening in the early stages of Nanomsg's development. These discussions are currently about adding administrative functionality and giving Nanomsg a config file. It's something that it's ancestor, ZeroMQ, doesn't have.
nanomsg is meant to be a part of networking stack. Right now it's in user-space library, but the long-term prospect is to make it part of the kernel.
