The action interface boils down to regular topics. So I do not see a reason
why it would not be possible. You can checkout Orocos-ROS integration of
topics and ports in the new orocos_toolchain_ros stack:
svn co
http://svn.mech.kuleuven.be/repos/orocos/trunk/kul-ros-pkg/stacks/orocos_toolchain_ros orocos_toolchain_ros
It contains a seamless integration of the dataflow between both frameworks.
