OK, wasn't specifically worrying about security, but why do you see
this as being an issue?
Because subscribers are a form of code. TTW subscribers would be a
form of TTW code.
We already have persistent subscribers now, in a round about way.
There are global subscribers whos job it is to notify utilities of
certain events, making those utilities effective subscribers.
...and utilities being local utilities that exist in he zodb?
The problem I'm trying to get my head round would be how to make
the following hypothetical zcml actually work:
<subscriber for="Ix Ix"
What you would do is create a Python object that knows about this
path and then subscribe that.
...and, from there, how to make it so a ZCatalog could have a tab
saying "subscribe to the following events"...
From there you wouldn't need that. The subscriber that you
registered in ZCML would notify the catalog.
To see an example, look at
zope.app.catalog.catalog.indexDocSubscriber and the way it is
registered in ZCML.
