I’ve got an idea (icio says it’s already been done, and Signifer bashed it).
Anyways, I think Shared Objects could be used instead of cookies… you could send content from JS to Flash easily (this is already common). It would be stored in the user’s computer, and would be accessible from then on… always, and easily.
Another important thing is… the cookies are available in every browser. For example, the background color of the header on Kirupa… I change it, and can see the new colors in every browser I have.
So… watcha think? It’s never been done so that it was easy to use…
