Linking existing Aegir installations into multiserver

I have a few Aegir installations that I use for various purposes - one on a production server, one in my local development environment, and one on an Amazon EC2 instance that I use for staging. It would be nice if I could push (clone / migrate) sites between these servers, for obvious reasons.

I read the documentation on remote servers, but I'm still unclear on some points. Let's say I want to make my local development installation the 'master' - is it possible to convert the other two installations into slaves? More importantly, will I still be able to access those two Aegir front-ends directly (clients need to be able to access them, for instance)?
