hmmm... interesting. But really, to write some client software that stores and provides read/write of the common "social content" (pics, blog posts, writing on the wall etc) in common standard RESTful way is such a far fetched dream?
It could be simple as www.mysite.com/diaspora/albums or www.mysite.com/diaspora/wall.
Even Obama can handle it. (Not to mention 4 dedicated CS grads)
