grub 1.99: no TFTP-booting when GRUB is locally installed --- why?

[René Kuligowski]

Apparently, GRUB's network capabilities are only designed to be  
loaded as an etherboot/PXE image itself.  There is currently no  
possibility (at least, none that I could derive) to install GRUB on a  
host, obtain a DHCP config and TFTP-boot a remotely served kernel  
that attaches its filesystems and swap space via NFS and swapd.  An  
example of a bootloader supporting this method is eg. Petitboot on  
the PS3, or some m68k and ix86 based bootloaders (for which I'd have  
to look up their names, sorry --- once installed, always worked).   
This method would be most useful in GRUB --- diskless clients could  
load GRUB from CMOS or VRAM, thin clients/desktops could use  
alternate systems to their locally installed ones *WITHOUT* the need  
to install them locally, centralized kernel/fs hosting for common  
environments with the most recent updates/patches.
Please add this boot method as soon as possible.
