Do Aldiko and Moon+'s ability to add an OPDS catalog not work on a rooted NST?
I have a server in my basement hosting my library. I use CalibretoOPDS to generate both OPDS and HTML catalogs. It's a 'dead' list, in the sense that there's no decent searching, but I have access to it basically anywhere. I can expose it publicly as I'm using Apache and can easily password protect that directory.
There's a Calibre PHP app, that I may move to, just so I can search my library before downloading.
I also use FolderSync to move audiobooks, music, and pictures to my portable devices. I guess I could add epubs to the list if the above doesn't work.
On my server, I have a root folder for each mobile device, then subfolders for audiobooks, music, etc. I have parallel folders on my mobile devices. I run FolderSync on each mobile devices with 2 'folder pairs' for each matching pair of folders. One is SMB, runs locally every night, the other is SFTP, and runs only on demand.
To move something to a mobile device, I just copy it to the appropriate folder on my server, and everything happens 'automatically' - unless I'm on the road, at which point i have to trigger the synchronization.
BTW, for SFTP on windows, I'm having best luck with Sysax 'Multi Server'. Not open source, but you can get a personal use license for free. (As a side note, Aldiko, and maybe Moon+, allow me to specify a port, so I could, but don't currently, set this up to use a commonly-not-blocked port, like 443. I'll do this if I get blocked. FTP is often blocked, also BTW)
I do all this now for a smartphone and a tablet. I recently decided I wanted a specific-purpose reader with e-ink. The NST jumped right out as the right choice. I'm figuring I'll root mine as soon as I get it and so these same things with it, but I'm just planning to use it as a reader (well and maybe limited browsing as I sometimes do that with my library before downloading via OPDS).
Hoping this is more helpful than confusing.
