yes, that's possible - but I don't think you can limit a certain 
authentication type to a pagetree. You could probably achieve that by 
using a if-condition with domain-check in your ext_localconf.php and 
only activate those auth-services that are available for the domain.

The auth-service of typo3 is working like this:
- it checks which services are available and orders them by importance
- then it asks one after another to check for a valid authentication
- if the service-module doesn't give back a success message, the next 
service-module is asked

So it's kind of aggregating all available auth-mechanisms until one 
succeeds.

I think so - if you code the authentication service yourself.

But this question might be more suitable for the dev-list I think.
