On another WP multisite, they have a top bar on their sites (like here: http://tinamarias.com/) where all heir blogs are listed, in a carousel.
I have tried to create a copy of it here: http://test8.bloggerspoint.dk - but i can't get it to work.
The top bar on tinamarias.com also show the current blog, you are visiting, and then i noticed that they're using an modified version of a plugin called "jQuery Carousel Plugin". The modified version looks like this: http://pastebin.com/rHrQRRas
I don't know how i can get it to work..
