fsserver:
fsclient:
The fsclient library provides a billy.Filesystem that talks to a gRPC server. The fsserver library provides a gRPC server that talks to a billy.Filesystem.
This allows you to access a remote filesystem as if it were local.
In fsserver you can access the gRPC peer from the context and return a different filesystem for different peers. You're expected to perform authentication at or before this layer.
The Billy interface isn't ideal for this, but I didn't want to introduce a 15th standard.
