Actually, when I heard their idea, my thought was 'Wow, I could write that. It'd take a long time, but I could do it. Wish I'd thought of it first.'
With enough work, it would be as easy to set up (or easier) than any other blog. The connections to other diaspora instances would be as easy as logging into OpenID... Just visit their page, put in your URL, request a link, and wait for the other person to grant it. It could also be done the other way with putting their link into your blog, and having the backend take care of it. I'm sure there are other ways, too.
So yeah, it could work. Not in that short amount of time, but it could work.
