Hi David,

SPDK (http://spdk.io) has a BSD-licensed userspace NVMe over Fabrics target
that could be used as a starting point.

Any questions around dual licensing the Linux kernel implementation should
go to the NVM Express Working Group.  The Linux kernel implementation was a
joint development effort from several NVM Express member companies - not
just Intel.
