Colleagues:

Version 7 of the iFCP protocol specification was submitted on 11/21/01 for
inclusion in the IETF archive. Pending the IETF announcement of
availability, versions of the document can be obtained from the T11 document
archive at: 

ftp://209.26.30.221/t11/docs/01-495v3.pdf -- created with markups visible

This version partially addresses the comments received from David Black as
discussed below. A number of issues are still open and will be addressed in
the next release.
