Google Books client - How does "reading positions sync" work?
 

Hi,

The Google Books app asks for synchronization capabilities to sync the last place I have been reading between Android devices.

Did anyone already sniff the network traffic or looked at some API description to see how this synchronization is being done? Especially, what the key for identifying books and reading positions might be?

I would really like to sync last read positions between my HTC Desire and a tablet I might buy later, but I am not really keen on uploading my epubs to google for this to work :cool:

Also, it would be nice if Aldiko and Calibre would have support for this feature :D


Regards,
Hakan
