Sound via Screen Sharing?

When connected to another Mac remotely via Screen Sharing, is it possible to hear the audio from the remote computer?

I have a PowerBook I use to control a Mac Pro from another room, and I'd like to hear what I'd hear if I was sitting at the Pro through the PB speakers.

I think the only sound you could receive from Screen Sharing would be a buddy from iChat. Someone correct me if I'm wrong
