Forgive me if I've missed it mentioned, but it looks like the option
is only being removed from the LiveCD.  Using the netinstall.iso is
still available and would be a more efficient way of doing network
installs anyway (9.5M vs 685M).

Unless things have changed since I messed with network installs (which
is has been a while), all you really need is some way to boot the
kernel and initrd files.  It doesn't matter if you start with grub,
lilo, syslinux, etc.  I remember using the boot loader of an existing
system to start the network install (but I don't remember what version
it was) on a machine without a working optical drive.

The issues you saw with grub being installed on the USB stick instead
of the HDD are a bigger concern in my book.  I wonder if you you have
better luck installing GRUB on the HDD MBR, booting from the HDD and
using grub to load the kernel and initrd off the USB stick.
