Indeed, the fix to roscpp is in ROS 1.0.1 and foreign_relay lives in
the boxturtle sandbox
(https://code.ros.org/svn/wg-ros-pkg/branches/trunk_boxturtle/sandbox).

I did a fair bit of hacking in foreign_relay a few weeks back and
can't guarantee the state of things.  But there should be something in
there that will do what you want.
