Couple of comments/questions, I'm referencing lines from the wiki page
below:

> Heat is going through a refactor in the next cycle

This is not true - the community have told us they want specific new
functionality, which we are aiming to provide, but we are not doing a full
refactor or rewrite - there will be incremental additions leading to new
features, probably including the ability for users to specify resource
definitions via templates, and probably initial support for an alternate
template syntax (the dsl discussion you mention)

We will not be dropping support for our existing CFN-compatible template
format, and any changes made to our internal data-model will be incremental
to minimise the risk of regressions - ie we absolutely will maintain our
existing functionality.

Can you clarify what "guest takes over" means - do you have a special
in-instance agent which handles securing the DB?

I'm interested in understanding why you see the initial
install/configuration (which can be handled by Heat) as a separate step
from the subsequent "secures db" step.

Thanks,

Steve
