The length of this chapter speaks for itself. Distributed COM lets you build distributed network applications in Python without changing a line of code.
There is of course a great deal more to DCOM than this. More can be done, and there are also a number of caveats about machine configuration. In particular, designing a robust multiuser server architecture is a complex subject in any language; it will almost certainly involve COM singletons and either threads or an event loop for handling multiple simultaneous connections. Chapter 12, provides detailed instructions for configuring DCOM for both Python clients and servers and explains the background to the application we just distributed.
