Seems that I managed to somewhat solve 2 and 3. Here is a piece of my
reminders file:

SET _trigdate evaltrig("Saturday", max(today() - 7, '2010-05-16'))
SET _deferred _trigdate < today()
REM [choose(_deferred+1, _trigdate, today())] \
MSG Perform software update[choose(_deferred+1, "", " (" + _trigdate
+ ")")]

I have a new question about using remind. Is there a way to print
reminders active just today (without piping remind's output to grep)?
And, in addition, is it possible to print all reminders active next N
days without duplicates? 

Best regards,
Eugene.
