I believe you can set your preferences on the macromedia site to deny all flash cookies. This will screw up the functionality of sites you visit though, like ebay and paypal, but I believe you can still get by. I believe there's also an app for OS X called Flush which delete flash cookies, but that's for the Mac. I'm kind of curious if it works if you decide to install OS X on the Ipad.
I was just searching through my apps on my Android tablet and found an icon for adobe flash player settings, I clicked on it and in the settings there is an option to never save flash cookies!
