Can I use SMART with my AoE devices?

The early Coraid products like the EtherDrive PATA blades simply passed ATA commands through to the attached PATA disk, including SMART commands. While there was no way to ask the aoe driver to send SMART commands, one could ask aoeping to send SMART commands. The aoeping manpage has more information. The Coraid SR and VS storage appliances present AoE targets that are LUNs, not corresponding to a specific disk. The SR supports SMART internally, on its command line, but the AoE LUNs do not support SMART.
