BeMo Terminal Service application for Project Professional is a SaaS application allowing users to run Project Professional 2010 without having to install it on a local desktop computer. If you have your own licensed instance of Project Professional 2010 running on your desktop, there is no need to use BeMo Terminal Service application for Project Professional.
Project documents stored in Project Server 2010 can only be accessed through PWA. There is no direct connection of Project Professional 2010 with the documents stored in the documents library located at the Project Site (in PWA). As this limitation exists in Project Professional 2010 itself, one cannot access project documents via BeMo Terminal Service application for Project Professional.
In order to access the project documents, you have to log into the Project Server 2010 via PWA using Internet Explorer.
