Definitely interested in that blog post.

Building on that, have you thought about wrapping up the package as a
deb or rpm rather than just a tarball?

You get a few nice things from doing that:

* admin friendly tools for querying the state of machines like dpkg
* a pull based approach, which probably works better with a larger
number of machines
* Less reliance on all your machines being up when you push the tarball out
* pre and post install scripts as part of the package if you want them
* easier integration with tools like Chef and Puppet (it's just a package)
* easier management of dependencies between your app and supporting
services like say a Redis or MySQL upgrade

Shameless linking to my own blog I know but some more thoughts on there:

I'm building debs of Ruby apps using Jenkins at the moment, but I'm
not yet happy with all the bundler stuff I have. Would love to see
what you're doing and integrate it with what I have. I know lots of
people who would appreciate an off-the-github approach to this
particular hoop jumping exercise.
