The project managment will be undertaken by the investigators. The project is small enough that little formal management structure is necessary. The investigators are currently working on the EU FET-funded Mobile Resource Guarantees (MRG) project and will adopt the successful management approach of the MRG project for this project. As in our current project, we will have regularly scheduled meetings of the project investigators and the research assistants and we will share designs, documents and software using CVS archiving. CVS supports remote networked file-sharing so that the investigators can collaborate when travelling or visiting another site.
