Samples of Upfront Websites

Hi,
I like to know the possibilities of Upfront and WPMUDEV Plug-Ins. Can you please give me some links to websites build with Upfront and Plugins. Or do you have a Gallery/Portfolio of websites? Also please give a link on How to Use Upfront.... like topics.

This will be inspirational to kickstart using it. I searched the a lot in Google and didn't found any.
