Calibre would probably have to store bookmarks for a variety of formats or somehow get the last page read from a variety of devices/apps. Then there would have to be a method of keeping track of your different devices/apps and send the information to either all or whichever you choose.

AFAIK there is no way to automatically connect to a device wirelessly, the device has to connect to the content server although some may be able to be connected manually to calibre . And there is no automatic way to differentiate between two different kindle keyboards for example when they are hooked up via USB, and you can only have one connected at once.

Calibre will send files via USB and it may even send them over wireless? Syncing seems a bit more complex.
