All,

Just wanted to clarify the e-mail I sent out this morning.

We have no interest in contributing the source code of the policy analysis
package to Imperius, but we will make the analysis module to work with
Imperius and we will make the module available through other distribution
channels.
This requires Imperius to open hocks for the analysis module to access the
internals of Imperius and also to provide additional information needed by
the analysis module. Are people in the Imperius team interested to make
such changes?

Regards,

I agree: seems like a nice addition. -- David

Xiping,

I think this would be a great addition.

Can you define what you mean by applicability?

As in the same conditions elicit conflicting actions?
