FWIW, I think that's a useful characterization(*), but I disagree with your earlier statement that IM and email are level 0; they are level 2, as they both deal in transfer, not transport. i.e. an IM client and IM server have to agree on an application interface, not just a means of sending bits across a wire. Also FWIW, the Web has special status amoungst level 2 systems, as it is capable of engulfing all others. (*) curiously, it also synchs up very well with the IETF and OSI stack models; level 0 = transport, level 1 = session/presentation, level 2 = application. MB -- Mark Baker.
