[Zope3-Users] asynchronous events in Zope3 (was: crossbar switch for event)

[Markus Leist]

Hi all,

so let's be more concrete:

here is a first temporary freehand sketch of the 'event crossbar switch':
http://trac.ict-ok.org/browser/documentation/temporary/20070917_queue01.pdf

even more concrete for Obj1 and Obj3:
Obj1 should be an UPS.
the signal shoul be 'battery empty/shutdown now'
Obj3 should be a server.

The user can configure an additional short connect between Obj1 and Obj4. This
will shutdown Obj4 (e.g. another server) on next 'battery emplty'-event, too.

I'm working on this within the next few days - anybody additional ideas or 'wishes'?

Markus

ps.
e.g. an early definition of Obj1 will be:
