I want to give the option to the computer user, not have to change it on
the dhcp server. A PXE-booted grub menu would be great if one of the
choices could be to boot locally and another could be to network boot as
a thin client. Even better if another non-default choice could be to
boot into a network install.

Going this route, I'd rather not have to dedicate a partition. Is there
any way to put it in /boot along with a linux boot setup?
