That depends if you want the mechanism to be portable
or platform specific.  In Linux I guess you could use
message queues, pipes or shared memory.  In Win32
the easiest would be Memory Mapped Files.  I know
WIN32OLE makes it pretty easy to use Automation
Servers and writing a COM IDispatch interface to
Win32 Memory Mapped Files wouldn't be difficult
(of course if there's a Win32 API library then you
could skip the COM part and just make the API
calls for the file mapping etc..)
