Wow, can you spare me 8GB of those?

For this to work you would need the following:
1. cdrom or netboot capabilities (or a lot of floppies)
2. an ssh udeb
3. build an initrd with all the network modules and ssh. The net
install initrd is probably a good starting point.
4. add the d-i udebs to the cd or have a source for them on the net
This is very very similar to what S390 wants. Except that they might
make do with telnetd instead of sshd.
After you log in you should be able to just strat up main-menu and
load the remaining udebs to finish the installation.
