hi,  
I am creating sec group (lets call it A\_SEC) using ec2\_group and this works fine. I need (later) to change existing sec group (B\_SEC) and add rules to grant access to whatever is using A\_SEC.

I cannot do this using ec2\_group as it complains about missing description. can anybody guide me how to do this. or maybe I should write my own module. are there any plans for ec2\_group\_roles?

thanks
