why not put a Forth bootscript on the bootp server instead of yaboot,
either write it to check the current time (in UTC which you can get
from newwer OF) and make a choice, or else simply have two different
versions of the script, one that boots macos, and one that boots a
tftp yaboot, then use a cronjob to rotate them at the appropriate
times on the bootp server.
