4 Developer Prototyping Process 1. Start by running multiplayer sample code. 2. Examine UML and extend samples. 3. Generate code for customized samples. 4. Examine critical metrics with diagnostic tools. 5. Round-trip engineering iterations refine code.

5 The Ninja Networking Developer Acceleration Kit streamlines the process of designing CORBA servants. Automated tools support roundtrip engineering, taking even non-corba developers from modelling the interfaces to generating the servant code.
