Hmm, this Peeker design is interesting..

+class PepperExtCrxFileSystemRendererHost
+    : public ppapi::host::ResourceHost,
+      public ppapi::host::FileSystemRegistry::FileSystemPeeker {
+ public:
+  PepperExtCrxFileSystemRendererHost(content::RendererPpapiHost* host,

+                                     PP_Resource resource);
+  virtual ~PepperExtCrxFileSystemRendererHost();
+
+  // ResourceHost override.
+  virtual int32_t OnResourceMessageReceived(
+      const IPC::Message& msg,

This can probably return const GURL&

Done.
