For most multimedia data, I'd say timeliness of delivery is more important
than reliability of delivery. That is, if you're taking too long delivering
one packet, you drop it and go on to the next one.

In terms of existing network protocol stacks, that means using a datagram-
oriented protocol (UDP or AppleTalk DDP), rather than a connection-oriented
one (TCP, ADSP). This also means lower overall network overhead.
