Syndicate FS Capabilities Synchronous vs Asynchronous reads o Asynchronous: small files o Synchronous: large files  byte-range request  good for distributed workloads Read-Only and Read-Write support o Read-specific and Write-specific URLs o Read-only clients don't serve content o Read-only clients can be anonymous Multiple writers per Syndicate Volume o Globally-unique Syndicate UID as file owner
