Is the connection manager api considered 'stable' yet? Last I knew it 
was still undergoing a lot of development.

Wouldn't it be possible to adapt the existing tcp connection setup code 
to work for Iwarp without using the connection manager? Most of the time 
when I test IB networks, I just bind to ethernet eth0 interfaces anyway.
