html 5 - to offer full clipboard control? (for discussion)

I get it. Security becomes an issue with allowing a website to Paste content onto a users clipboard. I have yet to find a reliable way to do that, that doesn't involve on the subject-to-change per the current version, soon-to-stop-working Flash way of doing开发者_开发技巧 it.

Perfect world: the 1st time a website tries to use a user's clipboard, prompt him or her with "site ABC wants to copy content on your clipboard, do you want to allow?" with "always trust ABC" as a checkbox, would be great. Best of both worlds.

Summary question for discussion: will html 5 make it easier to utilize the users' clipboard?

The HTML5 spec currently contains one mention of the word 'clipboard' and that is in relation to change events so: Probably not.
