Restricting Project List and Search Results in OAF pages to display only those projects on which a u

Hi,

In R12 Project Management Self Service pages can we restrict Project List and Project Search Result in OAF pages to only those projects on which a user logged in is an active project key member as of sysdate. 

(employee attached to fnd user is a key member on project). 

For Ex: On Project P1, KM1 is a key member from 01-DEC-2011 to 20-JAN-2012

When the user(KM1) logs on 21-JAN-2012, KM1 is no longer an active key member on the project P1, we need to restrict the project P1 so that it doesn't in the project list or even in the Project Search Result of KM1.
