Copia vs NookStudy/Blackboard in College Market?

From The Digital Reader:

I admit we don’t really know what Blackboard adds (to NookStudy), but I think it’s reasonable to assume that students will be able to share their notes, highlights, and other annotations with other students. This could be very similar to what Copia does. Of course, no one has seen either app is talking about it, so what do we know.

If I’m right, then right now Copia are in a race with B&N. They need to get their app out of beta and on to the market before B&N release Nookstudy. If they don’t, then Copia have pretty much lost the academic market. ...
