Where are you updating the version information at? And how are you generating

It depends on the package, but let's say it's in a version.txt file.  Your
implication is correct though - if setup.py is parsing that file to calculate
the version key, it can also do the same and calculate the download_url value.

I'm really just trying to get a sense of your workflow to see if I can make any changes to improve the process for it.

One of the big problems with download_url is that the data in setup.py is used in (and influences the content of) the final dist file. This means that inside of a setup.py you won't know what the hash of the final file is. So it's difficult for a setup.py based workflow with external urls to provide md5 sums for the files which means that pip and friends can't verify that no body modified the download in transit.
