1. Win32s IS an extension to Windows 3.1 which allows Win32-based applications to run under Windows 3.1. Win32s supports all the Win32 APIs, but only a subset provides functionality under Windows 3.1. Those APIs that are not functional return ERROR_CALL_NOT_IMPLEMENTED.  
2. This is technically not a subsystem. 
3. Cannot be created on Win16, Windows 95 and MS-DOS workstations, but can be opened.  
4. The POSIX subsystem supports FIFO queues, which do not interoperate with Microsoft's implementation of named pipes.  
5. Through the Windows sockets API. 
6. Currently BSD-style sockets are under consideration for the POSIX subsystem.  
7. Windows 95 supports the RPC 1 protocol only. The NetBios protocol is not supported. Namedpipe servers are not supported.  
8. Win32s version 1.1 provides network support through Universal Thunks. 
9. Under Win32s, WM_COPYDATA does not actually copy the data -- it only translates the pointers to the data. If the receiving application changes the buffer, then the data is changed for both applications.  
10. OLE objects created in a Win32 service must be in the same user context as a logged on user that wishes to use them. Any attempt to access these objects from a different user context will result in failure. For example, a service that runs under the LocalSystem account creates an object that an application running in Domain\User's context attempts to access will fail.  

I know this is an old thread, but if anybody can add Linux and Mac to the Interprocess Communication chart, it would be more complete.
