The DietORB for the PalmPilot uses IIOP as a transport protocol. We started
with the absolute minimum functionality, and then expanded very
conservatively. The result is an 'ORB' that marshals the basic IDL data
types, and is able to properly invoke methods on full CORBA services. The
ORB is combined into library for the PalmPilot. We generally invoke methods
across wireless modems, such as the Minstrel, or Metricom's Ricochet. A
brief description of how to use the package is available.
