Here's how I'd set it up: when somebody signs the petition, they could have a few 'additional level of commitment' options, inluding their intent not to see Ep. 3 theatrically, not to purchase the SE-only DVDs, and for the truly hardcore, their intent to withold any monetary support from all Lucas-related endeavors (possibly including all films created with the help of ILM and/or Skywalker Sound) until the OT DVD is announced. Then, when somebody goes to the petition stat page, they can see not only the overall number of signers, but also how many have signed up for each 'additional commitment' option. Of course, it'd be something of a problem introducing these options this late in the game, particularly in terms of allowing those who have already signed the main petition to sign on as boycotters.
