decent example of configuring+deploying rails app with poolparty?

[Joey]

I can't seem to find a decently up-to-date example of configuring and
deploying a rails app environment with poolparty. The examples
embedded in the source appear to be out of date, and the various other
examples and blog posts also refer to deprecated functionality.

This seems to be a recent and relatively complete example of deploying
a rails app via chef, but is not poolparty-specific:

http://www.opscode.com/blog/2010/05/06/data-driven-application-deployment-with-chef/

In particular, it relies on "data bags" to provide the application's
configuration details, and I'm not sure how to achieve the same
functionality in poolparty (in a 'solo' environment rather than chef
client/server).

Does anyone know how to adapt this to poolparty, or know of a
different example of deploying a complete rails app via poolparty?

Thanks
