Would be great that marketo offers an automated mechanism that pops up on a web site a small window woth a message such as (from silverpop)
"To enable certain features and improve your experience with us, this site requires cookies to be stored on your computer. Please check the box and click

privacy notice."
and a check box.
The message above would need to be translatable or have multiple versions. A flag in the munchkin code would indicate which version of the message to prompt so that companies with multiple web site would be able to adapt to local regulations and languages.
If the person accepts cookies, we do not prompt it next time. If she does not, no cookie is stored, but the message is prompted again at next visit.
