Just one more thing about portal_alarms: it has a minute-level granularity 
IIRC, so it won't fit a 5 second periodicity.

Basically, portal_activities is designed for one-shot execution. Of course, 
you can make an activity create another one, making it periodic.
You can plan an alarm for execution at a future date by providing an "at_date" 
parameter to "activate" method. Ex:
  context.activate(at_date=DateTime("2009-01-01 00:00:00")).doSomething()
Note that it will only give a lower bound to its possible execution, it might 
execute later. That imprecision depends on activity load (how many pending 
activities, ...) and timerserver tic rate (set in your zope.conf, by default 
it's one tic every 5 seconds).

For your other questions, I'm afraid don't know these areas well enough to 
give an answer.
