8. Things in progress
• Transient repo storage
• Refactored ‘sync’ (decoupled from repo)
• Apps: Medical device interface, serverless
XMPP, automatic photo sharing

9. On the radar
• Opportunistic caching support
• CDN-quality transaction logging framework
• Generic link level encap with hybrid ARQ

10. Community development
• Many exciting things happening. E.g.,
‣ NDN ospf-n, python bindings, device control
& video streaming apps, ns3 simulator
‣ ANR-Connect simulator, QoS framework
‣ U. Basel CCN-lite
‣ ...
• PARC interested in setting up a clearinghouse
to promote & connect these efforts.

11. Commercialization
• Operator and vendor research interest.
• ENC (Emerging Networks Consortium)
looking at scenarios and use cases.
• Need people solving real problems to
evolve from ‘research’ to ‘advanced
development’ stage.
• Eventually standardize based on ‘rough
consensus and running code’ (the world
may not need another 3GPP IMS)
