Yes; I'm currently working on porting rbootd to my Linux system...
Current state of progress is that it correctly receives the 
Send Server ID packet from my HP 9000/340, and tries to send back
the response. *Something* gets sent, but the HP just repeats the Send
Server ID request. I conclude that something's wrong with my code for
writing packets to the ethernet... Unfortunately there is no
documentation
on how to do this under Linux :-(
I'll stick something up on my web site (http://mnementh.trin.cam.ac.uk/)
over the weekend with further details, in case anybody's interested...
