Steve,

I'm not aware of any past or present discussion of IP _header_ compression in this wg. 

The IPPCP wg followed its charter, as even the wg name implies:

The IP Payload Compression Protocol Working Group will develop protocol specifications that make it possible to perform lossless compression on individual payloads before the payload is processed by a protocol that encrypts it
              ^^^^^^^^^^ 

True, the original version of the draft (RFC, soon, maybe) included the header as part of the compressed payload, but the wg decided to compress just the ULP portion of the datagram.

Regards,
avram
