AIUI the mopd in Linux was originally written for NetBSD so they could boot the
VAX port. It was then ported to Linux by I know not whom. Incidentally there
seems to be a bug in that version that breaks mopd -a on machines with more than
one ethernet card.

The Linux/MIPS guys have done some nice mods to it so that it can boot ELF
images direct without having to preprocess them first (I forget the URL but I
can find it (or provide binaries) if anyone's interested.)

I use mopd to boot my DECserver 200 as well as my MIPS DECstation (for
some reason Linux 2.4 sets the frag bit on all UDP packets which it doesn't like
so I can't use bootp).

My LATD package has a moprc program (written from the specs you mention) which 
allows a Linux user to remotely manage terminal servers and trigger remote boots
of machines too.
