Not having actually looked at the binary tz setup - I still work with
the raw data files - I'm not sure if each TZid has it's own full
expansion from the base generic rules? Is that the case Paul?

With large areas of the world NOW using a generic rule, one of the
American areas, or European time, I can envisage a 'distributor' that
provides only a current subset of timezone data? Perhaps even truncated
to 2010 and used for ICALENDAR/IEVENT current events. In much the same
way that the mechanism for monitoring 'version' comes out in the wash,
one that maps TZid to the core generic rules should also come out
naturally?
