using gmail authentication within dx_auth

[eluser]heylarson[/eluser]
this is my first project written in codeigniter so please excuse me if this question has been answered elsewhere. i have my site's email accounts hosted through gmail and would like to avoid users having to setup yet another account. is there some gmail api that i could integrate into dx_auth that will allow users to authenticate with their gmail credentials?

thanx in advance for any ideas...

well based on some initial web searching i believe i found the means. google provides a federated login through OpenID. On request from a third-party site, Google authenticates users who are signing in with an existing Google account, and returns to the third-party site an identifier that the site can use to recognize the user.

my next step is to read up on this, and find the means of integrating this into my site.

here's my reference: http://code.google.com/apis/accounts/docs/OpenID.html

if anyone has any experience using this, please post. thanx.
