Sound to good to be true? It is. 'What this does not do,' Root said (yes, that's his name), 'is the holy grail of instant messaging, which is to allow anybody on any network to send a message to anybody on any other network.' It seems that the system, which is aimed for corporations, involves some MS software which acts as an intermediary between the different systems. Sounds like a fancy version of all the open source IM clients out there."
