I'm just chucking ideas into the ring. I haven't spent a lot of time
analysing your requirements, just hoping to kindle a spark.
Thought about named pipes? When Unix used to have a 2GB file size
limit, I used a custom script that exported an Oracle database to a
named pipe, the output of which was compressed to a file (hopefully)
within the limit. If the file was still too large, split (1) came in
useful prior to the actual writing. I'm sure there are web references
out there somewhere.
