WordPress MU

Is there a way that a logged inn user can get a quick publish capability in the front end theme on a WPMU site?
Thinking about same quick publish that is on the dashboard. It could work in a similar way to facebook where you need to be logged in, and then you'd get a quick publish field somewhere on your page on the front end. Visitors and users whom are not logged in could have a commenting capability there, like on any normal post.

Any ideas around this?

Look at the TDO mini forms plugin.

Thanks.
