Given that any practical implementation has to interoperate with iCal,
the barrier to entry is high.  To what degree is this addressing actual
failures of iCal (e.g., where iCal is ambiguous) and to what degree is
it just *simpler* for the implementor?  (Coming from the world of SIP,
I've learned that things that are nightmarish for implementors are often
criticial to real-world use of the protocol) Ease of implementation is
nice, but given the need to interoperate with iCal for many years, it
has limited value.  Also, to what degree does the simplicity of
JSCalendar simply push work back into the interface between the
calendaring system and the JSCalendar interface?

I suspect that in practice, semantic upward-compatibility from iCal will
be important.  You mention in section 1 item 3, "a conversion between
the data formats is not guaranteed to be completed without losing
semantic meaning".  What exactly are the incompatibilities?
