Ideas for easy, PHP-style, Rails deployment (ala mod_rails)

Hi.

There has been a lot of fuss about Rails deployment lately. I've
written some ideas on my blog (http://izumi.plan99.net/blog/index.php/
2008/01/27/rails-deployment-wouldnt-it-be-great-if-it-worked-like-
this/) about how Rails deployment can be made dead-easy, i.e. PHP-
style upload-and-forget.

I would appreciate any feedback on my ideas.

Thanks.
