Yes, it should be easy to serialize the state using convertToRaw and/or convert it to HTML/Markdown/etc. I could imagine official helpers for this might be added. You can try the embedded photo experience in Facebook Notes at https://www.facebook.com/notes https://www.facebook.com/notes. I think it does essentially everything that you have described. (I believe we do keep at least one (possibly empty) block after each media object to allow putting the cursor there.) Mentions (like on Facebook) can be done easily with Draft's entities, and mentions that behave more like syntax highlighting (like on Twitter) can be easily done with decorators. Mobiledoc looks pretty awesome though. I hadn't seen it before this -- thanks for sharing.
