+1. lv2ftp isn's serious, just a test and benchmark of the sntllv2
+2. there are few stages:
+2.1 Simple v.1
+    This protocol is enough to donwload a directory subtree with files.
+2.1.1 Directory workout
+    * Open directory stream: (dir-open "<dir-name>")
+      * Return: error, or rapidly replies with (dir-stream <id>)
+    * Read directory entry: (dir-read <id>)
+      * Return: error, or rapidly replies with the following:
+        * (dir-end <id>)
+        * (dir-entry "<filename>" "<filetype>"), where filetype the following:
+          * regular - regular file
+          * directory - directory
+          * block - block device
+          * char - char device
+          * fifo - named pipe
+          * link - symbolic link
+          * socket - socket
+          * unknown - unknown file type
+     * Close directory entry: (dir-close <id>)
+       * Return: error or SNE_SUCCESS
+2.1.2 File workout
+     * Open file: (file-open "<file-name>")
+       * Return: error, or rapidly replies with (file-id <id>)
+     * Get simple stat: (file-stat <id>)
+       * Return error, or rapidle replies with (file-stat <id> <size>)
+     * Read file data: (file-read <id> <offset>)
+       * Return error, or rapidly replies with 30k(raw data, in base64 it will be more) (file-data <id> <offset> "<B64encoded data>")
+     * Close file: (file-close <id>)
+       * Return error or SNE_SUCCESS
