In our case its a slightly more strategic requirement. We'd very much appreciate some kind of visible plan/roadmap that maps out where dotLRN is headed and so forth.
In our case we've had quite a bit of interest from major clients in using this system for collaborative product and project development. As I'm sure you can see the functionality for dotLRN is virtually identical to what our customers are looking (we've nominally referred to it as dotWRK).
However, in these commercial environments our customers are a lot less keen/willing to engage to early and become embroiled in a project at beta stage. Therefore if I'm going to swing a sale I need to be pretty confident of the roadmap, divergences from what we'd like to acheive and therefore effort required from us.. (I think that makes sense).
So our requirement would be for a commercial roadmap (irrespective of the underyling technical communcation and progress).
