Opera's only chance in the market is to spread virally. To have an Opera user tell an IE/Firefox/Safari user about this cool new feature that they could both use if that IE/Firefox/Safari user would just switch to Opera. Looking at the howtos provided, it seems to me you only need Opera to host the solution and the rest is perfectly cromulent web-standards, that is: Any user with a JS-enabled browser should be able to hook up and use your app. This doesn't invalidate your point about spreading the word about being able to do cool stuff with Opera, but it does not require a full lockin either.
