Last week the URL Rewrite Module for IIS 7 was released, this could be useful for your Project Server and SharePoint Server deployment:
URL Rewriter for IIS 7.0 enables Web administrators to create powerful rules to implement URLs that are easier for users to remember and easier for search engines to find.
