The (expensive) solutions here typically involve IP over ATM, with forward error correction provided at the transport layer. This improves the reliability of your UDP stream considerably, since you don't have the option of application-level requests for retransmit. Furthermore, you can implement a certifiably low-risk system for retransmits using a separate ultra-low-bandwidth uplink that can raise a NACK on data errors that FEC can't handle. This is sufficient for unidirectional TCP streams to be wrapped. I mean, sure, you can fake it if you're not worried about someone connecting the wrong cable (potentially turning your system into a wonderful fountain of all the data you were trying to protect) and if you're willing to write custom application level protocols to handle significant amounts of data loss in transmission.
