I don't see why not. It looks like a standard Rack application so you could follow any guide to deploying rack applications, for example using Passenger (http://www.modrails.com/documentation.html) or Unicorn and nginx (http://blog.tomkersten.com/2010/11/14/nginx-unicorn-rvm-serv...).

You could run it anywhere, it is just a sinatra/rack app.
