What are two possible ways to achieve this goal?

You have a sandboxed SharePoint 2010 application for managing sales proposals. The application runs in a
hosted environment that does not allow direct access to external services or the installation of proxies or external
content types. The account status for your application is contained in a Customer Relationship Management
(CRM) system hosted on a separate server. The account status information is exposed via Web services.
You need to display account status from the CRM system in the form of dashboards, pie charts, and other reports to the users within your firewall.
