We've presented InHome, a peer-to-peer system that can significantly reduce external bandwidth usage by fetching data from local peers when available. Since many web requests are for data previously requested by another peer on the network, InHome eliminates these duplicate requests and ensures optimal use of outgoing network links.

InHome uses a novel scheme to guarantee low latency: Data-Oriented Chord. Here, pieces of data are stored as virtual nodes in the Chord ring, eliminating the layer of metadata present in most DHTs. Using Data-Oriented Chord balances low latency with minimal network overhead, preventing InHome's operation from having a significant impact on typical network activity.

InHome is well-timed for widespread adoption. Current hotly debated topics like Network Neutrality and Bittorrent Filtering are instigated by a lack of bandwidth capacity, and InHome provides an easy-to-deploy technical solution that realizes significant bandwidth savings.
