TiVoBridge is a packet repeater for both the TiVo discovery beacon and Multicast DNS (used in ZeroConf, Bonjour, Rendevous, etc.) protocols. It is intended as a way for TiVo boxes and other devices or programs that use either of those (normally single-subnet) protocols to see each other across routers in a complex local network.

A sample configuration is included for a two-router, three-subnet network, but the program is very flexible and can be made to work in a number of network configurations. TiVoBridge was developed under Linux, but the source code is fairly portable.
