When issuing an "--upgrade" option, can the "download_url" be checked automatically, or is there an existing way I can get a handle on that "download_url" variable to pass to easy_install? Any advice would be appreciated.

Check out the --find-links option:

easy_install -f http://some_url eggname

http://peak.telecommunity.com/DevCenter/EasyInstall#command-line-options

I know I can pass that, but it is a matter of introspecting an installed egg to find its download_url.

Eggs don't carry download URLs, they only carry dependency links, and only if the author specified them. If what you're saying is that you want to be able to check the page you originally got the egg from for updates, there isn't currently any way to do that, except to effectively maintain your own package index. It would probably be a better idea to gently encourage the package's author to run "setup.py register" on a regular basis to keep their PyPI listing up-to-date, since that helps everybody else, too.
