Facebook connect on Facebook iFrame apps

Hi,

Please pardon me if its too basic OR facebook itself doesn't allow such a thing with connect. Couldn't think of a better place to ask

Step 1: I have made an auction app in Drupal that used this module and it works perfectly. I can allow new users to register with their fb accounts and also, it automatically detects if I am logged into facebook

Step 2: I wanted that the same app run inside facebook (i.e. apps.facebook.com/AppName) so I used the iframe mode. Now the issue is that if I am already logged into the app from another tab, it shows fine but it does not sign in from inside the iframe

I figured that one possible reason can be that the xd_receiver.htm file is not in the location apps.facebook.com/AppName/xd_*.htm but rather on my own domain name... Do you think its possible to make it work if I simply create a menu callback that defines that creates the file on-the-fly?
