if you are talking a virtual interface, why would you use either?

define a driver that does page allocation tricks to move data between the client and the host for zero-copy communication. at that point you beat anything that's designed for a real network.

then you can pick what driver to run on top of this interface, SCSI, IP, custom depending on what you are trying to talk to on the other side.

As I wrote above, implementing an IB driver would allow to reuse a whole software stack (called OFED) and the implementation of several communication protocols. Yes it is possible to develop all this from scratch, but that is more or less like reinventing the wheel.
