414715 WordPressMU widget

I need a WordPress widget that shows posts from a specific blog at my WPMU network. In the settings for the widget when it is "live" i should be able to add a banner/image at the top. I should be able to add what blog in my WPMU network to pull posts from and how many posts that should be shown. It should also show a post thumbnail from the post it shows and the size of the thumb should be able to be set. The number of letters it should show from the post must also be changeable. The widget areas where i plan to use this widget variate in width so it must be able to use it in widgetareas with different width, so a function to choose the alignement of the banner would be great. Thanks
