Hi Daniel:

I think the aim is to have a basic header that looks like RH0 with a
record route. Then 6LoWPAN can work on compressing it using 6LowpAN
techniques. 
And we'll certainly commission more work to have our own labeling
system. But none of this should hold our base spec whatsoever!

cheers,
 
Pascal
