The NFS and SCSI groups have each defined a standard which Zach's proposal
abstracts into a common user API.
Distributed file systems tend to be rather unique and do not have similar
standard bodies, but a lot of them could hide server specific implementations
under the current proposed interfaces.
What is not a good idea is to drag out the core, simple copy offload discussion
for another 5 years to pull in every odd use case :)
