I am an engineer working at Intel on SPDK, and I can answer any technical questions you might have.
Currently SPDK consists of a usermode NVMe (PCIe-attached SSD) driver. We will soon be releasing a usermode driver for the Intel I/OAT DMA engine (copy offload hardware) that is available on some server platforms.
