As far as I can tell it's mostly a marketing distinction. Many Quadrics customers run with memory registration, and Mellanox could probably alter their firmware to not require registration. Myricom certainly can, and in fact Patrick Geoffrey claimed they were doing so in their MX software. The only one I know of that isn't that flexible is PathScale's InfiniPath. Ours is a pure hardware mechanism, but it requires memory registration and is clearly not an MMU.
