I would imagine a Canadian court has no jurisdiction over Boonex, since Boonex is out of Australia. Wouldn't a Canadian webmaster need to buy the software and mod it to comply with Canadian law?

It would be like if I allowed users to upload pirated movies. If I got copyright notices from the RIAA or the FTC, it would be my responsibility to comply with copyright laws and filter video uploads, and not the authors of Boonex.

If Boonex had to bend to every nation's rules and laws, then there see more really wouldn't be any software left.
