[Edu-sig] Question about Python - Social Networking Software

[csev]

I am looking for some social networking software for a course I am  
teaching next winter.  I would love for it to be Python.

In PHP - something like Elgg would be great.  It needs a Wiki, Blog,  
RSS feeds, etc etc.

Should I just use DJango with a few modules?  I worry that DJango is  
too much of a Mambo-clone - I want something that is user-centered  
(student centered) - not organization centered.

Something with good access controls - with the ability to have closed  
groups - would be a nice feature.

Thanks.
