I'm very interested in this thread and would contribute to the campaign. If there's a question of the "product" for Kickstarter, as was raised in an earlier thread, the product is the form letter.
I will say that I think that a letter would carry more weight actually coming from a real lawyers office, but having something pre-drafted will likely defer some cost.
It's probably best that the letter contains the legalese equivalent of
"an IP address is not a person". (also see
a recent US ruling)
If they get the court order and actually call people to court, the potential to make this case law in Canada is huge. Seek the support of the EFF then and start online fund-raising. Lots of people in Canada would love to see case law made here.
