First, if you use a shared blob directory, then the directory needs to
accessible on the client, either because the client is running on the same
machine as the server, or because you're using a distributed file system.

As you point out, the annoyingly tight permissions on created blobs means
that you need to run the client and server with the same users.  This
really should be configurable.  See Sean's reply. :)
