We can assure you that this is for real. We at Phusion have been working at this for quite some time now, and several of our beta testers include Rails core team members, as well as some of the largest RoR hosts on this planet ;-). And so far, the feedback has been overwhelmingly positive and we can't wait to share this with you guys. We do ask for your patience though, albeit for just a little longer.

Regarding documentation, we think you'll be more than pleased to see that we've gone the extra mile on this part. If anything, we hate bad documentation as well, so we really intended on tackling this with Passenger ;-). For more information regarding Passenger, be sure to keep a close eye out on http://phusion.nl, http://www.modrails.com, http://izumi.plan99.net/blog and http://ninh.nl as we'll be posting more about it the following few days/weeks.

I wouldn't get too excited without seeing some sort of actual documentation. Hopefully this is done ala-WSGI

On a random note, this is a really nice looking site design.
