You have a caching server (a separate machine) that caches files from servers that are far away. Some of the file servers it caches are synthetic. You mount one of them in /net. The server doesn't know that.

The dynamic nature of namespace works against such conventions.
Besides it would be nice to have a mechanism that could work in other
systems that use 9p.  File servers should be able to convey whether a
file is cache-able or not.

i'm not sure i follow this argument.  plan 9 namespaces are dynamic.
one could put the network devices anywhere, but they are conventionally
put on /net.  there are no "regular" files in /net.

perhaps if you gave a concrete example of why conventions can't sort
this out it would make more sense to me.  (i'm slow.)
