It asks for all the CDs first, there's no path through the install that
asks about a network mirror first (if anna uses a network mirror, this
isn't a full CD and so it doesn't ask for other full CDs, AIUI).

If you're on a corporate network and choose to use a mirror and this
works and yet the corporate network's policy doesn't allow it, than at
least three things are broken (a stupid policy that trusts random CDs
more than gpg signed data on the network, a flawed implementation in the
network, and a flawed adherance to that policy). Sorry, I can't take
that example too seriously as a goal to design for, although I'm sure
it's realistic.
If you're not on broadband and you choose to use a mirror, it takes
half an hour or more just to download the Packages file. Apt can
estimate this reaonably well so you shouldn't even need to wait, you can
just see in the progress bar estimate that the network is slow[1]
This is a good indication that you made the wrong choice -- installing
any significant tasks will take much longer -- and all that's really
needed then is a Cancel button so you can move on to using a CD instead.
By the way, the above stuff is also nice to have if your network is fast
but you choose a bad mirror.

[1] apt's estimate is not currently exposed to the user by apt-setup,
but this should be fixable by using debconf-apt-progress.
