As the draft API spec <http://mkruisselbrink.github.io/navigator-connect/> currently stands, initial connection and ongoing communication are all asynchronous. This is how we have initially envisioned the API, but there isn't any major impediment to considering a synchronous piece if a compelling use case supports it.
One key part of the API that remains to be sorted out is what will happen when a web origin attempts to connect to a Service Worker that is not registered. This connection attempt could either fail—perhaps without any indication of whether the SW was not installed or rather the connection was rejected for some other reason—or it could lead to downloading and registering the SW. Maybe this scenario necessitates UI in some cases. This is very much an open question.
