Ok.  I meant to say that ROHC is dealing with the TCP header.  I do not 
mind that.

I mind if header compression touches the IP header.

For information only, I wonder where is ROHC used in implementations in 
products.  A ROHC option in the linux kernel, or a ROHC wireshark 
dissectors are good indicators of its use.
