Run the Buzz relay on an always-on Mac and the desktop app on the workstation you sit at, with Ansible driving both halves. The relay hosts a community — Buzz’s name for a shared workspace — and is the shared log every person and every agent in it writes to, so it wants a machine that does not close.
