Probably not with this Patent from DS http://www.freepatentsonline.com/6108751.pdf I believe that DS are fine with 1-wire masters being created but that they would take action against people creating slaves that are claimed to be 1-wire compliant. I wonder if they would be ok if for each slave that was created, the unique device ID was taken from a real part that was destroyed or at least never released into the wild so that there would never be a clash, or whether they simply don't want others to use their protocol without a license, period.
