2) In your conversations and literature studies have you found any intellectual property claims that might limit access to 'join' methodology (Microsoft patents ?).
I received clear confirmations from researchers at both Microsoft Research and Moscova INRIA that there is no patent for Join-Calculus and Cw. Also i do not have / use any source code from Cw, although my implementation is based on the design and ideas from Cw paper. Quote from researcher at Microsoft: "There's was a deliberate decision not to patent anything related to Polyphonic C# or the Comega concurrency constructs (other bits of Comega may have been patented). Nor are there any patents on the Joins library. So I think you are perfectly safe there." Thanks Yigong
