%X Process algebras like CSP and CCS inspired the original
   occam model of communication and process encapsulation.
   Later the pi\-calculus and various treatments handling
   mobility in CSP added support for mobility, as realised in
   practical programming systems such as occam\-pi, JCSP, CHP
   and Sufrin\[rs]s CSO, which allow a rather abstract notion
   of motion of processes and channel ends between parents
   or owners. Milner\[rs]s Space and Motion of Communicating
   Agents on the other hand describes the bigraph framework,
   which makes location more of a first\-class citizen of the
   calculus and evolves through reaction rules which rewrite
   both place and link graphs of matching sections of a system
   state, allowing more dramatic dynamic reconfigurations of a
   system than simple process spawning or migration. I consider
   the tractability of the notation, and to what extent the
   additional flexibility reflects or elicits
   desirable programming paradigms.
