In the era of Ubiquitous Computing and world–wide data transfer mobility, as an innovative aspect of professional activities, imposes new and complex problems of mobile and distributed access to information, services, and on–line negotiations for this purpose. This paper restricts itself to presenting a distributed and location–dependent RBAC approach which is multi–layered. Also an adapted form of Administration Nets [24] is presented which allows the scheduling of distributed on–line processes for automated location– dependent negotiating procedures, and for proving their correctness. Examples are discussed in some detail.
