I think there are more examples than ceph. From my memory, HP adapted their message queue implementation to be compatible with Marconi.

It would seem that where people do use the code (maybe they were out first), they should be rewarded for being compatible with the API.

BTW, it's going to be a squeeze on Monday at the board to get this into 1h30
