Isn't there a CHECKSUMS.MD5 file in the directory where the ISO image is
placed on the FTP site ?

It might be nice if there were a utility that could pull the ISO in small
slices just like any distribution and then put it back together.  For that
matter, couldn't the ISO image be made into a distribution that sysinstall
would understand ?  To download it, you would :

- run sysinstall
- change the installation direction in the options dialog to match the one
you want to download (4.0-RELEASE in this case)
- select a custom distribution with just the "ISO image" dist
- select "commit"

sysinstall could then download the dist as many small chunks, and the
"install" procedure would just be to glue the chunks back together and stick
it in a known place on the HD.
