[TenTec] open source

Carl ... I was employed by IBM during the 80's when the PC was developed and 
rose to fame. Their BIOS code was reverse engineered many times and while we 
are talking about a radio, the concept is identical. There were some law 
suits filed by IBM and they only won when it was actually proven that the 
defendants had prior knowledge or access to IBM code and used it. Most of 
those cases were lost by big blue and a whole industry of "clones" was the 
result.
