I've done some digging into this issue.  I normally don't log in
directly as root, but sudo or su to run up2date.

The yumRepo backend (which up2date uses to comminicate with a yum
repository) uses the python urllib and urllib2 modules.  Both of
them respect the *_proxy environment variables.  The yumRepo backend
doesn't grab the proxy preferences from the up2date configuration, tho.

I found that no matter how I set it, the http_proxy environment
var wasn't getting to up2date.  A print of os.environ showed a pristine
environment.  After much poking around in the up2date_client python
code, I had a *duh* moment.

consolehelper

A quick path check showed that I was running /usr/bin/up2date, linked
to consolehelper, which cleans the environment and calls
/usr/sbin/up2date.  Running /usr/sbin/up2date with http_proxy set
allowed the yumRepo backend the ability to communicate through the
proxies here without any problems.

The real solution would be to re-write the yumRepo backend to honor
the up2date configuration and call urllib/urllib2 with the appropriate
proxies, but this works for now.  I started patching yumRepo, but I'm 
not a python hacker, and didn't want to duplicate effort if this is
already being worked on.

I hope this helps others who have been stuck with this.
