As far as out of box modules you might look at the "MyProfile" module that was originally create by DNNFusion and has very recently been bought by the folks that make Active Forums. It is intended to be a social network style module like MySpace. I don't think of it is highly flexible or mature but could fit what you are looking for perhaps.
I was looking for something like this myself recently for a slightly different purpose. I was creating a real estate site and wanted each listing to have its own gallery of pictures and a nice looking gallery at that since they were million dollar plus homes. That coupled with the fact that the users entering listings are very non-technical meant they wouldn't be capable of doing page additions etc. via DNN admin.
I really did not find solutions that fit that scenario myself. What I ended up doing was purchasing Ultra Media Gallery which is a great module and I think the most popular module as far as sales at Snowcovered it concerned. Then I used XMOD for the data entry portions including a separate form module for the image uploads then I did an integration of the two so that the media gallery got its picture data from the XMod data. It worked very well.
Unfortunately this is not an out of box solution for you. If you are a programmer or have some money you can invest to have this done for you you might find it works very well for you. If that is something you are considering we could talk further.
Good luck with the site!
