Nah, actually we should say:
Boot from any URL. (file://, http://, ftp://)
with
Kernel Image in any binary format (ELF, GZIP, COFF)
I found the most basic problem of current bootloaders (GRUB, Etherboot,
even LinuxBIOS) is that
they focus too much in low-level implementation detail. The overall
design looks like it is implemented
in assembly, no a higher level language called C. The designer does not
use much data abstraction,
or OO techinques you can found in modern O.S. kernel. This makes adding
a new feature into the
bootloader very diffcult.
