Save notes to a notebook in evernote.
The new Atlas publishing option creates static HTML from mind maps, and you can then easily pull this into evernote. See http://discover.mindmup.com/atlas
Does this give you what you need, or is there something else that we need to consider regarding Evernote?

need to be able to import from evernote too
I'm agnostic about this being able to share specifically with Evernote but would love some more cloud options.
Sharing with Evernote and/or Box would make this a killer business app.
