[ec2-beta] Get security group from within instance?

[Darren Govoni]

Hi,
  Thanks for the links. I did review the EC2 tools documentation before,
but so far, none of the tools appear to report the security group for
the instance it is running in, without first knowing the instance id. 

I need to know the security group from WITHIN the running instance using
a script/command (e.g. get-my-security-group). I can easily find the
group from outside the instance _after_ it is running. :)

The meta-data link you supplied seems to be dead though.

thank you again!
Darren
