Will there be a hotsyncing/download app a la itunes for the Librem 5?
Can you give an example of what such an app would do?
HotSync was the old Palm Pilot sync software.
I haven’t heard anything regarding USB sync so far. I’m sure it would be possible via command line, but I don’t expect this will be convenient at launch.
Most modern sync happens wirelessly over the network and from what I’ve seen this will be available in a reasonably convenient way.
I can recommend using Nextcloud, which is exactly this
I don’t know itunes, but both Nextcloud or syncthing https://syncthing.net are nice mechanisms for syncing of content. Caldav and Webdav are also working well with nextcloud, for instance.
