This topic was discussed
in this thread which started about a year and a half ago. Given the momentum and usefulness of apps like Gospel Library and LDS Tools, it's sad and a little disturbing to read that certain local leaders had attempted to ban electronic devices in their wards and stakes as recently as January 2012. Indeed, the newest version of the LDS Standard Works is currently
only available in an electronic form!
I was a bit of a pioneer in my ward 9 years ago when I ditched my paper scriptures and started bringing a Pocket PC to Sunday meetings. I'm not sure what others thought I was doing at first but they quickly learned that as I was looking at my handheld device I was fully following the discussion and, in many cases, was doing more with footnotes and cross-references than anyone else was. Today, I'm always carrying an iPad to church and at least half our quorum uses smart phones to follow along. There really is no need to make rules about device etiquette in our ward. People use them. They work. If anything, it enhances the lessons rather than creating a distraction.
As far as the other topic of this thread... it's common practice around here for funeral directors to set up their own recorders to make audio recordings of funerals in chapels. They usually attach their own microphone to the one on the podium rather than use the jack that was hard-wired into the sound system
for the express purpose of recording what goes through the PA system. While these things aren't supposed to be live-streamed, it seems that you could easily record the audio (which is not strictly prohibited) and send that audio file to someone via the Internet within moments after the funeral takes place (which, again, is not strictly prohibited... but it certainly approaches the same result as a "broadcast" without actually being "live"). And, of course, to the listener in a far-off place and another time zone, the experience of listening to the "podcast" or the "broadcast" may seem identical.
