I'm building a Rails app that includes live group chat. I've heard Juggernaut is the best option for this. Does it work on Heroku?
They did have experimental node.js support but it seems to be in closed beta for the timebeing. Expect a release soon.

I have minimal sysadmin skills but managed to set up an Ubuntu 10.04 environment with relative ease. http://purebreeze.com/2011/03/adding-realtime-push-updates-to-agileista-using-juggernaut/
The 'easiest' option is probably to use Pusher but probably not as fun or cost effective.
UPDATED
Heroku now fully support node.js
Here's a gist from the juggernaut author showing how he set up juggernaut on Heroku:

I will also update my blog post shortly to reflect getting up and running.
It's much easier now!
