Scripts for booting FreeBSD images from the install ISO for use in Jenkins?

Hi,

For the BSD DevSummit in May, one of the items
on our agenda:

https://wiki.freebsd.org/201405DevSummit/Jenkins

is to talk about writing scripts which can take a FreeBSD ISO image,
and then boot it and run it on a remote system or in a VM
to install the OS.  After the OS is up, we would like to run tests.
All of this would be triggered from Jenkins.

Does anyone have scripts which can do this?
Can they be contributed to the Jenkins effort on FreeBSD?

If you have scripts in Python, Ruby, Bourne shell, etc. are all fine,
or even recipes in automation frameworks like Puppet, Ansible, Chef,
SaltStack, etc.,
please let us know! :)
