Portable DIstributed Systems Using Node on "Routers"
summary
Claim: run Node on routers to cut latency by eliminating hops and serve apps from the edge. Uses Tessel 2 on OpenWrt, Node’s dgram UDP + mDNS for discovery, and local HTTP; demonstrates a live camera stream and a multicast button→LED toggle that mostly works despite occasional jank. Notes concrete constraints: 64 MB RAM, 32 MB flash, bufferbloat on conference Wi‑Fi, 42 ms NY–SF RTT and an anecdote of 570 Wi‑Fi base stations to justify local networks.
