Ability to listen on multiple ports (80 + 3000)

[jakeonrails]

My team uses some sort of alias in their /etc/hosts or whatever to make http://oursite.dev:3000 go to localhost:3000. They manually start their servers. That's fine, but I'd prefer to use POW, and a simple http://oursite.dev.

The problem is that we have some hardcoded URLs in development, or external services, that want to go to http://oursite.dev:3000.

I would like for http://oursite.dev:3000 to work just like http://oursite.dev.

Basically, I want POW to listen to requests on port 3000 and port 80 and map them to the same Rack app.

I tried:

$ cd ~/.pow
$ echo 'http://oursite.dev:3000' > oursite
$ echo 'http://oursite.dev' > oursite

But.... that obviously doesn't work - as it's trying to forward requests to http://oursite.dev (as in: the POW domain represented by the textfile ~/.pow/oursite) to http://oursite.dev:3000 and there's nothing listening to that URL/port combination.

Does anyone know of any way to make this work?
