While there might be systems with no requirements for dynamic
rule uploading, there are others that simply cannot be managed
without that capability.
I'd like to distinguish some types of rule dynamicism, though.
The simple one is "active/deactivate rule". The other is
"incorporate new rule." And, at the workshop, we noted
that changing the state of a variable in a rule activation
can be a substitute for adding a rule. I.e., if we have
the variable "list of banned users", then the action
"add Alice to the list of banned users" and the
rule "if current_user is a member of banned_users then
deny access" is equivalent to the rule
"if user is Alice then deny access".
This hints at why I believe that we need to define
some common set of state variables for actions to
manipulate.

Maybe a general division of where the rule engine
is useful for control and the dynamic aspects of control
is needed.

regardless of other benefits - I don't think allowing dynamic rule upload
would be very helpful in this situation (due to additional delay of the
process).
I guess mechanism that trigger different set of rules depending on
changing conditions might be more helpful - if possible.
would be interesting to hear ideas on this tomorrow,
