Using OpenID login style instead of a seperated block
Hi Dave,
First! Thanks for this neat project.
Second:
Why don't you use a OpenID like approach for loging in instead of creating a new block.
This would allow developers to have the "regular" login block with a line/button with for OpenID and another line/button for Facebook.
It is a bad Usability approach to seperate as a different function what as an equal function.
See the following modules for inspiration on this one: http://drupal.org/project/comfortid
These are also neat links not totaly related: http://drupal.org/node/351066

I will add that. But please
I will add that. But please understand there are good reasons for a seperate block.
For one, some sites have no login block, just a connect button.
Another, when a user is logged on she can still click the connect button in order to link an existing drupal account with facebook.
