> In Chrome, a SharedWorker is reachable from any WebKit process, whereas a SharedScript would only be reachable within a WebKit process.  This is an interesting distinction, and I can imagine some use cases for SharedWorker that SharedScript could not address.  (This distinction arises because we did not want to build a script proxy between WebKit processes as that would be quite costly.)

What you seem to be implying is that a "SharedScript" would not actually achieve the one thing it is intended to gain -- a common context for all instances of a page.
