Not to mention that there is no gurantee of routing consistency on the 
public Internet. One day, you may get 1,200 KB / second to your favorite 
Gentoo mirror, and the next it is routed over some 64k leased line as a 
backup to a failed OC-12.

Does this mean that it doesn't work? No. Most of the time, you can get by 
with Voice over the Public Internet w/ acceptable quality, but there is no 
gurantee.

With a private circuit, using QOS, you have a lot MORE control. Of course, 
it doesn't solve ALL the issues, but it certainly hits my top three.
