There’s a new gem called passenger which makes it very easy to deploy your rails application on a Apache2 server. Here is the website of the project: Passenger
There’s also a short screencast you can watch to see how easy rails deployment can be: Passenger Screencast (the video is made by Ryan Bates from railscasts so the voice should sound familiar 
)
Ah, das ist ja mal klasse.
Gibt’s das in irgendeiner gearteten Form auch für Windows? Also vorkompiliert?
So far there seems to be no support for windows: http://www.modrails.com/documentation/Users%20guide.html#_supported_operating_systems
