Hi Anthony

I think I got that link from somebody else just recently, I remember it
was the first time I'd heard of ATS.

Absolutely - let me know if there's anything I can help with.

When you say "we're using Metalink as the mirror list", what do you
mean?  One annoying item in my setup is the parsing of the HTML mirror
page - you wouldn't happen to know of a way of retrieving the mirror
list in XML format?

Switching off segmented downloading is interesting too, but I wanted an
environment where the regular openSUSE install process would work with
zero modifications.  For instance, imagine a student wanting to install
a PC in the lab - grab the NET-install ISO, copy it to a USB stick and
boot.  No need to know the proxy, no need to know about a switch for
segmented downloading, just pop in the USB stick and go with the
defaults.  Same goes for later updates and additional software - that
Squid is helping out in the background should be 100% transparent.

I thought curl already had it?  openSUSE's zypper uses curl under the
covers.
