Why change the name of the coin. Changing the name for anything other than legal reasons is rediculous.
Like I said one really can't exclude that legal problems could occur. But I'm no lawyer and don't know if it would be a problem in some countries or even worldwide. (After all it's a global movement)
I think if the Pirate Political Party adopts the coin it would be a move in the right direction. Regardless of how altruistic the party is or isn't. The party just needs a media spin doctor to promote their cause in a positive direction.
I didn't quite get the input on the last part. Could you try being more specific?
