That's correct but there are other e-readers that support a similar technology, such as Pocketbook, or the Arta Tech Inkbooks.

While not supported by the plugin (yet), many readers support syncing new content via services like Dropbox, therefore you could use a service that uploads file via e-mail to Dropbox.

Overall the workflow part of converting an RSS feed item to an E-Reader format (i.e. ePub or Mobi) is covered, it seems viable to add more delivery mechanisms. Due to the market I am in (Europe) I've investigated the possibility to deliver to the Tolino platform via libraries like https://github.com/hzulla/tolino-python, but also adding Dropbox might be a possibility.
