</div>It's my contention that frequently large web apps are doing more than<br>
just polling for data. They're trying to maintain complex data<br>
structures that they pass up to the UI. The programming model of<br>
SharedWorkers makes this difficult. Take the chat client in Gmail, for<br>
example. It's much more complex than passing stock quotes from a<br>
worker to the UI.</blockquote><div><br></div><div>I understand that this isn't helpful for existing web apps like Gmail, but I think a MVC type model will work pretty nicely with shared workers. It's just the transition phase that's going to be painful.</div>
<div><br></div><div>This idea of a hidden page just seems like a big hack to support today's applications. If it were adapted into the spec, I think 5 years from now we'd be very sorry that it was.</div><div><br>
