I haven't looked at the code in a long time.  I'm guessing that the 
tftp and bootp services expect to recieve a packet that contains 
some binary data in it as well (dhcp does this).  If you don't send 
exactly the proper data, the server may not even respond to you.  
I'm not positive about tftp, but I believe a full blown plugin would 
have to be written just for bootp/dhcp because of the protocol 
involved.
