This is quite old, and subsequent discussions have happened which indicate
a slightly different approach, e.g this thread here where I discuss
approaches to signalling an AutoScalingGroup to remove a specific group
member.  As Angus has noted, ResourceGroup already allows this via a
different interface.

Probably the first thing is to provide a more detailed description of your
use-case.

I'll try to revive the AutoScalingGroup signal patch mentioned in the
thread above this week, it's been around for a while and is probably needed
for any interface where we pass data in to influence AutoScalingGroup
adjustment behaviour asynchronously (e.g not via the template definition).
