1Abstract-By developing demonstrators and performing smallscale user trials, we found various opportunities and pitfalls for deploying Personal Networks (PNs) on a commercial basis. The demonstrators were created using as many as possible legacy devices and proven technologies. They deal with applications in the health sector, home services, tourism, and the transportation sector. This paper describes the various architectures and our experiences with the end users and the technology. We conclude that context awareness, service discovery, and content management are very important in PNs and that a Personal Network Provider role is necessary to realize these functions under the assumptions we made.The PNPay Travel demonstrator suggests that PN service platforms provide an opportunity to develop true trans-sector services.

This paper describes issues related to the integration of IMS and DVB-RCS satellite networks. DVB-RCS is studied as an access network variant for IMS in addition to the already known cellular, wireless and cable access networks. Although combining IMS and DVB-RCS seems a practical solution for communication and content delivery several issues must be addressed in order to make the integration effective. The main areas of research are quality of service integration and multicast integration. Specifically, integration of the IMS QoS architecture (PCC) and the control protocol (C2P) of satellite communication is studied, and also how IP multicast can be integrated with the satellite content distribution mechanism.
