Actually in BI 4.1 Analysis OLAP now does support RRI as a sender.... ie you can right click on a cell and pass context to whatever RRI reciever has been specified for the query.
See http://scn.sap.com/docs/DOC-44327 for what's new for AOLAP in BI 4.1 and also http://scn.sap.com/docs/DOC-44827 for a specific description of using AOLAP with RRI.
