My main concern is that interface changes be driven by the application needs and not the hardware implementation (or even application implementation), especially when selected out of convenience.

So far, we've discussed adding:

- completion model
- 'commit or sync or flush' operation
- 'commit or sync or flush' flags
- memory registration flag

Maybe the best answers are provider specific options or prototype interfaces, with software simulation.
