I'm assuming Paul was asking about daapd not ifconfig. Anyway, I never quite got it working to my satisfaction. I had memory issues (not enough of it) and never found a multicast responder that didn't suck. Now that many of us have memory upgrades and daapd appears to have mDNS builtin it is probably an easier proposition, but I haven't had time to look into it again. Someone (tonyc?) also sent me a PM a while back asking about it and it sounded like he was going to try and get it working, not sure if anything ever came of that.
Once the new car smell wears off ('05 Mustang GT getting delivered on Wednesday) and I get an empeg installed I may try to find time to get it working again.
