Nothing disturbs me more than watching a patent system devised to further the science and well-being of the people being construed to do exactly the opposite. Thank God for the GPL. What we really need is an "open-hardware" initiative that documents hardware developments and could be used to contest frivolous patents such as this one clearly is. -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
