Hmm thinking about this some more.

Rather than implement a tcp stack we could just use UDP.

How about the following.
PXELinux goes to menu and listens on port 12345
I send a UDP packet from the tftp server saying what are your options?
PXELinux replies with 1...,2....,3...,4....
I reply with a confirmation that I recieved
WHILE response == false && menusend < 3
  PXELinux sends menu list.
I send command boot 1
PXE boots to option 1

Main problem I envisage is that this is insecure no password or password 
in plain text. On the flip side is it really important after all
we are on a private network & worst case is that a malicious user could 
rebuilt a system after sniffing the password.
