Can Insoshi be customised to create a student-group hub?

[Alec Taylor]

Good Morning,

I'd like to utilise a social-network site for student-groups using
only Free and Open-Source tools.

Mockup of the student-group homepage (dashboard):

Can Insoshi be customised to give me these features, if not, could you
recommend a package (i.e. a CMS Distribution, a CMS+ a set of modules,
a non-CMS social-network &etc.) that will enable me to do this?

Thanks for all suggestions & information,

Alec Taylor

PS: Would also be great if the login could be integrated with Facebook (API).
