Never mind, I misread what you were proposing. The biggest concerns I can see is: * I doubt twitter will let you just take their API * No matter how much you try to simplify it, managing this is going to require work. It doesn't seem worth the work just so you can own your 140 character blurbs. I can see businesses wanting twitter on their intranet, but there are already many solutions for this. I haven't looked too much into it, but you might want to look at the diaspora project as it shares a lot of these concepts.
