Unfortunately HTTP boot only works as far as the kernel: UEFI fetches
loader.efi, the loader fetches and runs the kernel over HTTP -- and then
you need to use NFS to mount the filesystem (or have a local root
filesystem).
UEFI also has RamDisk support, but I don't think that's for remote
ISO/disk files, just local files.
