The effort for legacy compatibility in building a network stack in the BIOS if it hasn't been done already is pretty monumental and probably not the direction we want to go in.
Any points on how to do the latter would be much appreciated.
Thanks

Out of curiosity, is this a limitation to what is possible in the BIOS or that nobody has found the need to do this sort of remote control using the BIOS yet?
There are a few things that you would need to consider.
For legacy compatibility you require a VGA BIOS with a network backend.
For a better solution, do what Ron suggested and put Linux in flash.
For the legacy solution, there exists a VGA BIOS with a serial port backend called SGABIOS, which you could build upon. SGABIOS is open source.
You would have to develop packet drivers for the network adapters which you want to work. You also need an IP stack. And you would have to make it all work in a BIOS environment, without any OS.
It is doable, but it is no small task.
