Sync Sideloaded (free ebook) Content + Bookmark/Last Read on iDevices and PC

[newuzertoday]

I'm at my wit's end trying to achieve the following:

Sync - Last read/Bookmarks
Content - Sideloaded/non-purchased free ebooks
Devices - sync and read content on iDevices and PC

I've found the following limitations:

1. Kobo and Nook - Will only sync purchased content
2. Kindle (Amazon) - Only supports syncing Personal Documents on Kindle Fire, Kindle Keyboard, Kindle Touch, Kindle for Android/iOS. Kindle Personal Documents Service is currently not supported on other free Kindle Reading Applications. i.e. - does not support Kindle for PC
3. iBooks (iCloud) - only supports iDevices (unable to read synced iCloud content/books in iTunes)

There has to be a way to achieve this. I greatly appreciate any input!!!

I have the same need. Tons of non-DRM ebooks, want sync between Mac and iOS, Kindle and maybe other devices.
All works between Kindle and iOS, but not i the Amazon Cloud reader or the Mac OS version ...

Sites like catalog.im and BookFusion.com seems to offer sync of notes/read status etc, but I guess there's no way to push/pull that to/from a dedicated reader (eInk) device? (Except use a web browser on the device -- which I assume is not optimal.)

How about's Sony T2's sync with Evernote? Does it work well? Is it easy to upload/fetch notes or highlights?
How about bookmarks and/or read status/furthest page read?

I'm looking for something like this for Android & pc. I don't care if the library is centralized (I'd prefer to have the books locally on the devices anyway for offline reading) but I just want to be able to sync my reading position between Kindle Fire, pc, and android phone, for non-Amazon books.

And I would like it synced between Kindle DX, iOS, Android and some web app (or native Mac/Linux program) ...
