Though I haven't been asked, I delayed my feed by 10 minutes so that I'm not responsible for tipping off anyone that may be using it for nefarious purposes. It's the suspicious activity/burglary type calls that mainly swayed me to do this.
If severe weather is imminent, I remove the added delay. I'm looking for better software though, I'm looping the audio through an old XP box running this: Audio Delay - Delay Radio Broadcasts - Sychnronize TV and Radio
It doesn't behave on newer machines though....haven't found any other free/cheap equivalents yet. It all seems to be geared toward professional broadcasters.
