Many people do not realize that TCP/IP is not mapped on _ANY_ wire directly, by the very nature of its architectural model. You DO NOT run TCP/IP over Ethernet, you run it over a link level protocol. In case of Ethernet, the protocol is relatively thin, with a big chunk of ARP is sort of considered a core part. For other links, such layer can be much thicker (for instance, ATM). Thus, it is NOT possible "to run TCP/IP over USB" without defining a certain mapping or protocol for this. Now, since you have to define some protocol, why not to use the a standard, such as CDC? There may be valid reasons in other cases, but it seems that CDC is not too broken, and is useable. -- Pete _______________________________________________________________ Hundreds of nodes, one monster rendering program.
