Microsoft Project Server 2010 customer dashboard and reports

I have a Sharepoint 2010 farm and am about to implement Project Server 2010.  As well as having a corporate intranet web app with Sharepoint, we want to have customer extranet web apps as well.  One of the things we want to do with Project is not only use it for our internal project management, but also to create dashboards and reports for our customers giving them a controlled view of where we are at.  Is this type of functionality readily available with Project Server and Sharepoint or will it require additional products or custom development?  

Also, should we host our Project Server web sites separately for each customer on their extranet web apps, or can we host it on our intranet and just publish dashboards and reports from the site to the different customers for their projects?  Thanks for the help!
