I know some people are working on iWARP devices though this could be done 
on the OpenRDMA source work (still a work in progress) which supports both 
iWARP and IB.


BTW, I second Tom, et. al. push to use an API to abstract this and avoid 
having to permute every subsystem to work for a given device.  The RNIC PI 
is intended to provide abstraction for iWARP / IB hardware to a very large 
extent (think of this as a standard verbs interface).  IT API / DAPL 
provide another layer of abstraction and can be used to integrate 
subsystems either over the RNIC PI or whatever verbs API people desire.
