The H.GCP audio call was held today, 18 ports called in including a group
from the TIPHON meeting.

The working model
Individuals have will be working up submissions to be review by the entire
group at the next audio call.  The objective is that the principals involved
will collaborate off line initially, post the results to the SG16 reflector
for comments and a final version will be posted for discussion in an audio
call.   The result of that final review will be added into the H.GCP by the
editor.  Every effort will be made to resolve issues but if they cannot they
must be presented in Santiago.

Work items
The following work items were identified and individuals who expressed an
interest in working on them are noted.
