Rails 3 and Devise: Omniauth vs. Facebook Connect

I am currently using Devise+Omniauth on my Rails 3 app to authenticate users. My client saw this and doesn't like how omniauth redirects you away from the site. He wants something like on digg.com, which I believe uses facebook connect to authenticate (and opens in a popup instead of redirecting).

What are some arguements for my client to keep him using the Omniauth method? Why is it better than Facebook connect.

And failing that, are there any good resources for logging users in with a facebook connect popup wi开发者_如何学运维ndow? Or really anything involving facebook and a popup.

Thanks!

OmniAuth supports login via the Facebook Javascript SDK, which works through a popup. You just need to include the right files. I don't remember all the details, but this should help:
