I can never figure out which side of this argument to be on. The basic version idea seems sound, but the problem is that for various reasons, the version number never ends up getting moved. For example, if I recall, FC-PH seemed to go through many version numbers long before it was ever widely implemented, and now it's stabilized at version 4.3. I have never known any implementations that did anything other than 4.3. In ST, we went back and forth numerous times. We ultimately decided that we were going to stipulate that a reved protocol was a new protocol, so no version negotiation would be necessary. The logic for ST went that hardware accelerated protocols are on thin ice if they think they can rev. You're almost always going to work around existing protocol bugs before you ever `fix' the protocol, so the standards committees better be sure of themselves before they forward. I think iSCSI is in this same position. FWIW Steph
