Subject: Re: [sca-assembly] eventing & policies

Hi Eric:
I wanted to acquaint you with our thinking, such as it is,  on eventing 
and policies.
I also wanted to say that I'm sceptical of policies on channels.

I was not commenting on other aspects of your note, so go ahead and 
raise the issue.
All the best, Ashok
