A Survey, Cloud File Sharing, and Object Augmentation

In this issue's Works-In-Progress department has three entries. The first is a request for community participation in a survey on indoor positioning systems for interactive, locative audio applications. The second entry presents a decentralized, peer-to-peer-based approach to cloud file sharing with encryption and data de-duplication. The final entry proposes an architecture for augmenting objects in the environment with visual icons and tags based on RFID, NFC, or QR Code technologies.
