ExpanDrive acts just like a USB drive plugged into your PC. Open, edit, and save files on remote computers from within your favorite programs—even when they are on a server half a world away.

calibre has a modular device driver design that makes adding support for different e-reader devices easy. At the moment, it has support for the SONY PRS 500/505/700, Cybook Gen 3, Amazon Kindle (1 and 2) and the iPhone (with the stanza reader software). Syncing supports updating metadata on the device from metadata in the library and the creation of collections on the device based on the tags defined in the library view. If an book has more than one format available, calibre automatically chooses the best format when uploading to the device.

It's intended for users with multiple computers on their desk since each system uses its own display. This project is a maintenance fork created to implementing patches and bug fixes to synergy.

Yes, even the iPhone. (Finally!)
