I did not phrase well: I am using portal 2.6.3, but the documentation of 2.6.3 doesn't include the "it is not possible to have many-to-one IPC", whereas the 2.2 documentation does.... So: I am using Portal 2.6.3, but read the warning in an older version of the docs. And indeed it still seems not possible to have many-to-one IPC out of the box in 2.6.3. So why did the jboss folks remove the warning from the docs? You will get an exception thrown if you try 1:m IPC.
