Deploy survey microsite to tpo infrastructure

I'd like to deploy the survey microsite on tpo infrastructure or eventually get a tpo subdomain and deploy it from greenhost.

If we prefer to deploy it on tpo, we would have to consider that it is a rails app. I'd need postgres and like to be able to install gem at user level. If possible I'd prefer to instal a local (user) version of ruby w/ rbenv.

Please let me know what we prefer regarding this and how I can help.
