I'm not sure what to tell you on this one. The Scheduling Framework is a work in progress and both it and quietly schemings version are incomplete at this time. With so many people working these interfaces (and some pretty large teams at that) and it still not being finished It clearly defines the complicated nature of the code.

You might want deep pockets because I imagine a complete version similar would be some seriously custom stuff and not likely to be offered up in a forum as a reply
