Notwithstanding the material that you'd found... if your goal is 
minimizing latency above all else adding another abstraction is probably 
not the best place to start.

patent problems, maintainability and interaction with other software are 
just a few issues that make it more problematic...

in one real example, intel nic TSO apparently broke tcp md5 for us just 
a couple days ago, though in a field unrelated to HPC...
