Please forgive me my ignorance, but why would you want to licence EterCAT at 
all? You would not be able to sell/advertise your product under the 
name/brand "EterCAT", but that would be all. Or is this a US speciality to 
get licensing problems when you did not sign a licensing contract that gives 
you that licensing problems in the first place?
