hello having a simple peerd is nice but having to constantly track the state-file might be problematic. it would be nice to allow peerd to execute commands on up/down events giving them on the command-line like: ``` peerd -ip 1.2.3.4 1.2.3.1 -onup="/path/to/command1 options {}" -ondown="/path/to/command2 options {}" ``` thx in advance
