Registration categories?

Hey Craig. Quick question.

I’m looking for an event registration plugin which allows two different categories of registrants. For instance, I’d like to have a certain subset of designated users to be able to register as tutors and another subset of users to be able to register as students. I would then go through and manually make up schedules to match up availability of tutors with a student’s requested time slot. Is this possible out of the box? If not, would it be possible for me to tweak things fairly easily?

Thanks much for any info.
