Three weeks of testing put multi-seat Wayland ahead of its applications

Sources: blinry.org, HN 49092112
Summary: A post on blinry.org reports three weeks of testing multi-seat setups on Wayland. The core Wayland protocol already binds every input event to a seat, and sway together with wayvnc supports transient seats end to end. The failures the author hits are in toolkits and applications, which assume one pointer and one keyboard.
Why it matters: It locates the blocker for multi-cursor collaboration in application and toolkit code rather than in the display stack, which changes who has to do the work.
