In the era of Ubiquitous Computing and world-wide data transfer mobility, as an innovative aspect of professional activities, imposes new andcomplex problems of mobile and distributed access to information,services, and on--line negotiations for this purpose. This paperrestricts itself to presenting a distributed and location--dependentRBAC approach which is multi--layered. Also an adapted form ofAdministration Nets is presented whichallows the scheduling of distributed on--line processes for automatedlocation--dependent negotiating procedures, and for provingtheir correctness. Examples are discussed in some detail.
