The TEFIS project aims to create an open platform for managing experiments across heterogeneous facilities related to future internet services. The platform will support the full lifecycle of service development and allow efficient combination of networking resources, living labs, and cloud computing resources. Several existing facilities are available in TEFIS, including Planetlab for network protocol evaluation, computational resources, and living labs for testing with real users. TEFIS will integrate and orchestrate experiments across these independent services. An open call is announced seeking pilot experiments that make use of at least two TEFIS facilities in areas beyond existing use cases, with funding available of up to 200k Euros per experiment. Proposals will be evaluated based on scientific excellence, implementation quality,
