I was under the impression that postMessage() was directed at a
particular window (or context). Does postMessage have a broadcast
capability?

Storage events have a broadcast'ish nature to them. Multiple windows
(or contexts) will receive storage events as changes are made to the
'storage' area. The sender does not need to know anything about the
receivers or of their existence.
