Okay, I didn't thought of that.
By the way, changing the MAC address seems not to work for the default
ne2k card while the e1000 card works. With ne2k everything works
(setting new MAC address, sending ARP replies with the new address)
except receiving packets sent to the new address. Maybe the MAC filter
in the ne2k emulation code is not updated. (tested with a
unpatched qemu 0.10.0)

Do you mean the mcast socket code in qemu or the way IP_MULTICAST_LOOP
works in the linux kernel?
