Valid hints for ftp:// and gsiftp:// URLs (aside from the std. ones):

  ftp_control_mode   extended|block|stream|compressed
                     (default extended for gsiftp:// URLs and stream for ftp:// URLs)

  parallelism        integer number of simultaneous threads connecting to
                     ftp server (default 1)

  striped_ftp        true|false or enable|disable; enables gsiftp striped data transfer

  tcp_buffer         integer size of tcp stream buffers in bytes

  transfer_type      ascii or binary (default binary)  

These *must* be specified at open time currently.
