Good. I'll work with the Freescale guys to get somewhere with the OF 
stuff - I know you're not so keen on this as the final solution, and I 
agree with you, but it looks like there might be sufficient critical 
mass here to finally do something about ppc boot records.

I bought one of these yesterday:


The remote control is trivially butchered and the buttons replaced with 
NPN transistors running off a PIC16F628 (well it will be by tonight). 
I've got a MAX233 doing RS232 to a PC for another project so am just 
reusing the comms to allow remote on/off control of 4-16 devices.
