UbiquiTalk is an open P2P platform that supports automatic peer discovery without requiring any infrastructure. Hence, UbiquiTalk can be used either within a network infrastructure or an adhoc network (e.g. Wifi).Each UbiquiTalk peer, named "host", can act either as a service provider or as a client or both. Users are provided an administration graphical interface to customize their respective hosts, and choose to export or import some services or none. The client part of UbiquiTalk GUI allows user to watch host detection and disparition. Moreover, it allows users to use some service provided by a particular host. Currently, we have two GUIs one for PDAs and the other for laptops and desktop computers.To use UbiquiTalk you can open it via the Tools Flap.More details and prebuild images are available on the UbiquiTalk homepage:http://csl.ensm-douai.fr/UbiquiTalk
