The thing about Xobni is that as much as I like it (having been doing interesting things with email for a very long time) and I think they are right to focus on Outlook (since it sux0r), I can't help thinking that Xobni is a _feature_ and not a company.
Perhaps the Xobni guys can talk about what makes them think that it's a stand alone company? Perhaps the answer is that they don't, perhaps they just hope Microsoft will buy them.
