Communication between L4Linux tasks and L4re tasks

Dear Developers, I have a simple question regarding the communication of L4Linux and L4re. I have already read previous entries but could not solve my problem. I am able to establish a communication between the tasks in L4re, but what I need is communication between a task that is running on L4Linux and a task that is running on L4re. How can I do this in simplest way? Any suggestions? Best Regards *Canberk*
