New teaser access permission

Hi,

I think it would be very useful to add a new permission to grant only teaser view access to some content.
I think It could be a new radio button under the view permission label (A T I D). A= allow, T=Teaser, I= Ignore, D=Disallow.

In multiterm nodes the T permission would act as a A permission, and if a node has A and T in distinct term for some role, I think the A would be the winer. Do you agree?

I know it would a bit of complication to the GUI but it would be very useful to allow, by example, anonymous users to see some content teaser listings but request them to register them in order to see the dull content.

This was achieved by using the premium ( http://drupal.org/project/premium )module, but it doesn't seem to be very active, and I think it would be better to have all permissions managed in an unique module.

What do you think?

Thanks for this grat module.-
