Bebo's "What are You Doing" provides 140 characters (same as Twitter) in which to say what you are doing, plus a countdown to say how many characters you have left. There's an aggregated page that shows all the messages from around your network, too. All that's missing: SMS integration. However, Bebo has already partnered with an SMS service for the creation of the Veronica's Widget, and I don't imagine they'll have trouble adding SMS support if the feature takes off (which it certainly will).
The nature of innovation is that everyone borrows from everyone else, so where is the line drawn?
