have a separate scheduler that is ultimately usable by other projects
inside OpenStack.  Currently Cinder has its own filter based scheduler
(duplicating scheduling code in 2 places seems silly), Neutron will need
scheduling services, there are multiple places where a common scheduling
service would be beneficial.

Agreed. Let's be clear :
- Nova needs to reduce its tech debt for scheduling : call it "n-sch effort"
- Nova needs to split its scheduler because it scales out development :
call it "n-sch split" (TBD at Vancouver)
- OpenStack needs a cross-project scheduler : call it "Gantt"

All efforts are intersected but are separate. Please don't get me wrong :
IMHO, all of them are useful.

goal is to create 1) a clean, robust interface along with 2) a scalable
architecture. Those improvements will 1) allow the scheduler to be split
cleanly, and 2) justify splitting it out. Splitting for the sake of
splitting is pointless.
