This has bugged me for a while

Just because spec choose to ignore offline deployment doesn't mean that 
the "verbs" applied to a stopped server don't have meaning to the 
average joe.

I an definitely against having more then one deploy tool.  It is like 
having a mail reader to read internet mail and a separate mail tool to 
read corporate mail.  Mail is mail and deployment is deployment.

I remember everyone liking the strategy, but I can't remember it myself 
anymore :)  Maybe David, can jog our memories.

The parallel universe scenario doesn't work anyway.  The generated CAR 
files are basically keyed to the server that generated them.  Maybe 
with a ton of work one day we will be able to do that, but for the 
foreseeable future it is not possible.
