If the compression or encryption algorithms change in a way that's incompatible with existing systems, you either have to change the protocol name, or add version numbering. I don't like the first solution since there are a limited number of protocol identifiers available, and the second requires your uucico to support ALL versions of the protocols, or reject connections with sites running older versions of the software (that you no longer support). -- Lyndon Nerenberg VE6BBM / Computing Services / Athabasca University {alberta,decwrl,lsuc}!atha!lyndon || lyndon@cs.AthabascaU.CA "I think every man should have a wife.
