The Enterprise-class WSRP Project (i.e Sun's implementation of OASIS WSRP vi spec) which is part of the Sun Java System Portal Server 7 has been open sourced.

The open-source code artifacts of the WSRP Project are from the Sun Portal's internal repository have been svn-checked-in to java.net.

The key features that are planned are

• Provide a WSRP v1 Producer.
• Provide a WSRP v1 Consumer that can consume Remote Portlets published by any WSRP v1 Producer.
• Provide support for Registries that allow publishing and discovery or remote portlet's meta-data.
• Provide support for user identity propagation and other security and policy capabilities between the Producer and the Consumer.
  

Here is WSRP Project on Java.net.

Currently only the WSRP Producer code is available. The WSRP Consumer and rest of the functionality's would be added shortly.

The WSRP producer right now is built over the Enterprise class Portlet Container Project on Java.net which was opensourced a short while ago.  But the project provides necessary abstraction that allows any other project to plug-into the WSRP Producer.

All these efforts (Portlet Container, WSRP, Portlet Repository &  JSF Portlet bridge) are part of the Portal Project .
