Comment:

 I don't personally think parsing the permissions returned by the FTP
 server is reliable enough, my reasoning being that it only gives a "maybe"
 answer - the FTP server can still block the operation, and it may still
 accept it based on other ACLs.

 FTP servers don't offer a method of testing if something can be done, they
 operate on a "try and see" method.
 The only way to tell if a file is writable is to attempt writing to it.

 Unfortunately I'm closing this as maybelater until a time where a patch
 can be offered that actually achieves the goal.
