Embedding an off-site <iframe> without sandboxing would in fact be more secure than embedding an off-site SWF. This is really an ecosystem issue, not a technology issue, as I understand it. Many of the significant video providers have gotten most of the popular blogging sites and sites that accept user-generated content to whitelist their SWFs. They are probably not motivated to do <iframe> embedding until the sites where content would be posted allow it, and the sites that allow posting content have little incentive to allow <iframe> embedding until video providers are offering it.

I think it would help to have a shared recommended approach to this, to break the logjam. Some of us at Apple are planning to talk to various media providers about it.
