This paper presents the design of CoFi, a novel architecture for supporting document editing and collaborative work over bandwidth-limited clients. CoFi combines the previously disjoint notions of consistency and fidelity in a unified architecture. CoFi enables bandwidth-limited clients to edit documents that are only partially present at the client (because parts of the documents were lossily transcoded, or only a portion of the document was fetched), and to propagate modifications incrementally by progressively increasing their fidelity.
