This is the initial release of support for "shared IP address" use for Classic/Blue Box and Mac OS X.

The Core OS components of this support include
   - this NKE (SharedIP)
   - changes to the Mac OS X  kernel

Until Classic/Blue Box is updated to include support for this mode of operation, it will continue to work as it has in the past: each "world" requires separate IP addresses, and is configured using the "usual mechanisms".  When an updated Classic/BlueBox package is available, accompanying notes will describe its use.
