I may be wrong but I believe that the redistribution clause should apply for OSS software to the software itself, and asking to open source some other stack component to use something in a given way is a very novel approach that IMHO is not going to be approved, or if it is, will be a big departure compared to what OSS is right now even in its most rigid incarnation of the AGPL. A similar but different clause would be: if you want to use that DB then you have to open source the application using it. In this way the friction looks more obvious. Disclosure: I'm going against my own interests saying that since would be cool for Redis Labs to queue in the same train. But I just believe it's not possible to do it in this way. Nothing against MongoDB itself.
