With all due respect, russellhltn, By the FCC definition, yes, it is. The transmission goes a lot further than that, it's just the poor antennas and low-sensitivity receive circuitry in the assistive listening receivers that reduce the range. The signal is not encrypted and can be received by anyone with a radio scanner or other receiver. A radio transmission of a few milliwatts can travel long distances, depending on frequency, antenna height, terrain, and other factors.
This is the reason that the translation systems in some church facilities use Infrared transmissions -- they are strictly line-of-sight (other than any possible signal leakage from the building wiring).
As the links to both the live stream and archived files are only accessible to people to whom I have sent the link, and that I have explicit approval from my local priesthood leadership, I'm not concerned, and only offered my expertise as a service to others. I haven't had any takers thus far, for what that's worth. I just personally felt it was well aligned with the Savior's instruction to "feed my sheep." We have a lot of people in our Stake that miss out on the fellowship and instruction of the meetings each week, and distributing a single audio cassette (by hand) every week is quite impractical.
If anyone is interested in the methods I'm using, feel free to send me a private message and I'll try to help you out -- it's been a real blessing to the members in my Ward and Stake.
My experiments so far to mute the stream when the sacrament mic is active haven't worked out yet (turns out the Ivie microphone consumes current from the mixer's phantom power all the time -- I was going to use that current to trigger an optoisolator to mute the audio or pause the stream), so that process has been manual so far. I'll post an update once I've solved that issue, either in software or hardware.
Of course, there isn't a mute on these links, which contain essentially the same audio: =-)
