In an ideal world, yes.

=> ~1GB / working day (8hrs)

=> < ~500MB per "uptime" for users booting for "a couple of hours a
day".

In practice, real world bandwidth is below this.

If you update an existing Fedora installation once a week, you'll
observe one update to typically be in the order of "some
100MBs" (occasionally several 100MBs).

Yes, this is one issue, but there are others.

For example: 
* broken mirrors
* periodic interrupts on DSL each 24hrs (=> Downloading isos is a matter
of syncs between these interrupts)
* other network load (downloading isn't the only usage of a system)
* mirrors being updated (and temporarily corrupted) right midst of a
"yum update".

Sorry - No, bandwidth makes a HUGE difference. 

The whole "way of working with Fedora" changes upon available bandwidth.

Now change to some X000 DSL - You'll probably very soon notice what I
said above.

Or change to ISDN/modem ... (ca. 1/10th of the bandwidth you currently
have) - Any major update is becoming a killer, in such situations.

If yum was working reliable, this would have been an option to me.

I resorted to "weekly updates" on weekends and "selective updates"
throughout weekdays.
