I wrote new failure detection algorithm based on heartbeat signal for
ng_one2many node. Features:

- automatic detection of failures;
- automatic detection of recoveries;
- detection of point of failure (see diagnostics in man page);
- configurable timing parameters of failure and recovery detection;
- you can create your own heartbeat packet or use default;
- you can set your rules for detecting that incoming packet is hearbeat  
- heartbeat algorithm can be used for different network layers (not only 
ethernet layer).

Patches for src and man page at
These patches for CURRENT, but you can compile patched files in 5.3.
