Hi, so we wanted to chime in a bit. We are building our node.js hosting platform (nodeJSCloud) on our own hardware, in a data center. Going this route vs using 3rd party hardware EC2 or Rackspace, gives us complete flexibility to do some nifty things. We are going to e-mail out a newsletter shortly with additional details.
For one Joyents no.de platform runs on their "accelerators" which are basically Solaris containers and there is a different package management system to deal with than you may be used to (they use pkgsrc) but it's pretty easy to figure out. Mostly you will just be using node package manager (npm) for node packages.
To help SSJS in getting main-stream adoption, we've coded some apps, Erbix Forms and Erbix Blog, written completely in JS, which we've open sourced and launched in the Erbix App Store ( https://secure.erbix.com/marketplace ).
New blog post just released: NodeFu - Free Hosting of Your Node.JS Apps In The Cloud! http://t.co/iHIuTtb < It's a step-by-step example for deploying a @Tropo node.js communications application on NodeFu!
Has anything of significance actually been developed on Node yet? Seems like there is a lot of excitement about it (like the early Rails days), but I haven't seen any sites announcing they're written in it.
