I'll  do. But will not have time before the draft cut-off deadline.

great! Thanks.

I was thinking of using some formating scheme in 64bit address format-
especially in the higher 48bit part - a crude example: <higher 32bit 
format>:<16bit-otherid><16bit hardware-id>. Having a formatting scheme
may help compressing the 64bit address into a 32bit address - thus
we can accomodate both originator and final destination address into the
64bit address space.
