Hi Pekka,

Did you get a chance to look over the proposal that is floating around
to use the flow label as a locally significant switching label?

Also, if the flow label can be used as an indication of 
classification at the source, then it can be used to 
decide preferential treatment in the network (hence the
20 bit DSCP extension proposal I guess -- which I have not read).
