So why does replica use 9P? Because it's *The Plan 9 Protocol*. If
*The Plan 9 Protocol* turns out to not serve our needs, we need to
figure out why.
You like to put forward devmnt's penchant for only having one
Tread/Twrite per process in flight at one time. I agree that this is a
problem, now, how do we fix it? All it needs is somebody willing to
rewrite devmnt... I think you may just have to rewrite mntrdwr to be
just a little smarter. Any takers?
9P as specified in the documentation might not necessarily be the
problem, but the implementation apparently is.

I don't see the NFS guys pretending that NFS is a good protocol for
transferring large files across high-latency links... I've only ever
heard of it being used in LAN environments. Yet 9P, which is not
really that dissimilar for NFS in basic concept, gets presented as
something we ought to be using over the Internet, for example to keep
our systems updated.
