Well ask yourself at what level would you like to be uniquely identified when visiting any website? I certainly don't want them to know my MAC address.
Have a look at the cfcookie tag. Also be aware that cfcookie cannot be used with cflocation. The concept with cookies is : 1) Landing page checks that there is no "votemade" cookie set. Sets a "cansetcookies" cookie and redirects to voting page. 2) Voting page checks for the "cansetcookies" (redirects to the we use cookies page" and that "votemade" is not set. 3) Vote is made and on the thank you page the "votemade" cookie is set.
