I did see this procedure.
However, the amopunt you retrieve on one trip is determined by the amount parameter. I'm currently retrieving in chunks of 1000 (i have to create another function to find out the most optimal chunk based on the lob size). I'm not sure what the maximum amount is though, i tried 10000 and it complained.
You also have to retrieve the correct amount of bytes near the end of the lob file otherwise you'll get a NO_DATA_FOUND exception.

I'm 85% there anyway, thanks for your comments.
