New Application Templates released for WSS V3 that might help your EPM Deployement:

Application templates are out-of-the-box custom scenarios tailored to address the needs and requirements of specific business processes or sets of tasks in organizations of any size. They can be applied to a task, such as managing a help desk or tracking a marketing campaign, to easily create a dedicated Web-based application for a more efficient and effective way of working.

While application templates can be used to solve particular business needs, they also provide a starting point for partners and developers looking to build deeper SharePoint-based solutions. The templates make use of Windows SharePoint Services 3.0 capabilities and are compatible with Microsoft Office SharePoint Designer 2007 to help make customization easier.
