Thanks for the prompt answer.
Your idea of using the “file://”  to host the file was exactly what I was
doing.  Then, I would place in the same folder a file containing the MD5
hash of the ISO.

If you have not yet changed the code to use the sha512 hash, I could do
that for you and create a pull request. Do you use Github to manage the
code?
This would only require you to how a file with the sha512 hash on
http://artifacts.opnfv.org/compass4nfv/colorado/opnfv-y.x.x.iso.sha512

Thanks again for all the help.
