We're hoping we can mobilize students as a marketing force, but we're not sure how to do it.

This first "application", Classlet Assignments, doesn't even require students to create their own account or visit the site (they can, if they prefer). How would you integrate the Facebook API or other social platforms with this application?

We'd also like to build other applications, including ones which target students, but we'd like to get one application right before we build others. Do you have a suggestion for a student-centric application (or features) which would drive viral adoption and could help convince schools to buy?

I am not sure buddy, but I know that is where students reside.

However, you guys could try several approaches:

-Bottom Up: Ask students to submit their .edu email or login via Facebook connect, and you will notify them once a class is added (this is a bit of false advertisement because at this point you don't even have ties with their professors). But as the number of students for each school becomes significant the school board will be more willing to listen ("75 students at XYZ sign up to ....").

-Top Down: Close the registration process and start to pitch to one school at the time. In other words, adopt an enterprise sale's model. It may take you much longer to close one sale, but you are guaranteed to have revenue from every client.

although as their model doesnt require the students to access the site (i.e. have an account) and seeing as most schools I know would never use Facebook to send out assignments it's probably not the way to go.
