Code review comment for lp:~frankban/juju-quickstart/new-machine-info

LGTM, couple of questions/comments. I think I follow the first one now.
If only you could order files in review to line up better.

File quickstart/app.py (right):

quickstart/app.py:420: collected_machine_changes = []
Can we use something like a hash keyed by machine_id (or something else
since it might not have an id per below) and then just update the
changes/state as it comes in to not need to sort/reverse/etc everything.
Just always keep the latest info for the key? I'm guessing not, but
curious as to the process.

these can be kvm as well correct? Should these be tested as part of this
or is there no difference other than the three chars?
