Given that technology context, it is certainly worth evaluating process development toolkits and process collaborations specified using pi calculus to see what they can do.
The rules have the form of typing rules for a basic concurrent language, the spi calculus [Abadi and Gordon 1997a; 1997b; 1998; 1999]; this calculus is an extension of the pi calculus [Milner et al.
