You failed to mention what you can do. Do you program at all? If so, which language?

Last time I checked (more than a year ago), the boost library does not support regions for memory mapped files, but the win32 API does. So you can write your own abstraction layer using the win32 API that gives you a more useful interface for your specific problem.
