Actually, my hope is to eliminate that business entirely by standardizing the on-the-wire representation for binary data; note the reference to send/receive routines in the original message. For integer data this is simple enough: network byte order will be it. I'm not sure yet what to do about float data.
Use IEEE floats or just report the representation in startup packet.
the X11 protocol does this for all data, even integers - the client expresses a wish what it wants and the server tells it what it gets (so two intel boxes need not to convert to "network byte order" at both ends).
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.
