People have been running multicast on XR (ASR9K) and 7600 since "forever". 
I'd be more worried about ME3600X and 3560/3750, but at least on the 
3560/3750 they're mature platforms so I'd imagine it works there as well.

How is multicast supposed to work without PIM?

What Gert was talking about was "Internet" multicast, ie multicast between 
ISPs. Watching NASA multicast streams for instance (I did this at my 
university in ~1995). Very few commercial ISPs support this.
