- ** 1. Check that we did the right thing with name_service and get_resource_name
- ** 2. Right now there is no "kill flow" in our GTNetS implementation. Do we
- ** need to do something about this?
- ** 3. We ignore the fact there is some max_duration on flows (see #2 above)
- ** 4. share_resources() returns a duration, not a date, right?
- ** 5. We don't suppoer "rates"
- ** 6. We don't update "remaining" for ongoing flows. Is it bad?
