IIOP/CDR behaves similarly for performance reasons- "receiver
makes it right". It also defines a representation for all of the
CORBA idl basic types, wide characters, fixed-point types,
structures, etc. A far-reaching, wild suggestion would be to
replace the postmaster with a CORBA-based server process with a
well defined interface. At a minimum, if a binary protocol is
the ultimate destination, perhaps some of the mapping of various
types could be borrowed from the specs.
