Prototype sends R objects (ggplot2 plots) from remote jobs into a Shiny UI using WebSockets, then persists and shares them with multiple viewers by writing to rethink DB. First version delivers plots to only the most recent session; after forking shiny doc collections to use rethink DB, multiple clients see the same state and closed tabs restore content. Remaining issues: socket server and Shiny must run in the same R process for auto-updates to work, and endpoint routing is still experimental.
