We thought about our proposal to cope better with security concerns as
other approaches. Our approach is completely client-based, so no
information has to be sent to the server, as compared to cookies or even
CC/PP, for example. I don't understand well if it is possible with CSS
what you describe above, namely to send information about computed
values to the server.
