The paper reports on an ongoing European Commission funded R&D project called ANEMONE [1] which aims at realizing a large-scale testbed for mobility technologies. This testbed will provide support of mobile users and devices, as well as enhanced services by integrating cutting edge IPv6 node and network mobility solutions. Among the key features of this deployment will be multihoming initiatives through the use of the current and emerging wireless access technologies. We review our progress of integrating existing testbeds and extensions covering campus and metropolitan areas with large spectrum of real end users, and discuss the conditions of creating this architecture.
