sql*plus cannot output binary data (answer is still 'no' ;-)) -- it has no capabilities for direct file output, just capturing what is spooled to the screen, which is always character data (and always contains newline characters)

you will need a program running on the client that opens the file, retrieves the BLOB into its variable(s), and writes the BLOB (probably in chunks) to the file

sorry, i forgot what you client tool of choice is -- perhaps you can post a new thread in c.d.o.tools for specifics with your chosen development tool (did you find out yet what would be the best interface for the customer?)
