Thanks.

After some discussion with Carsten, it seems that we may need both bits 
for Hop Limit compression. Current idea now is that 1-bit indicates 
compression, another bit indicates whether the elided Hop Limit is 63 or 
1. I originally thought we could do egress filtering based on the 
destination address, but Carsten thought that it missed the point of the 
Hop Limit. The cost is we utilize the reserved bit in the IPHC encoding 
and remove any flexibility it could have provided.

Right.

Sure.

Thanks.
