How far do I or can I transmit into the grid? How far do load changes from my house transfer into the grid? Surely my neighbors could detect 1us spikes not big

  I remember consumer devices from the 80s that allowed transmitting audio using mains. They were already outdated by the time I saw them in the 2000s. Me and some friends tested them and tried transmitting to a neighbours house (connected to the same electrical post) and had no success at all. There was just too much noise, coming from other houses. However with digital technology I'm sure you can get a much better range.

  Things like HomePlug GreenPHY are used for smart meters. (Also electric car charging for some inexplicable reason) I don't know how they're typically deployed but I'd think at least a few miles? It wouldn't make much sense to use if you'd have to have the receiver really close - just use wireless.

  Using ethernet-over-powerlines within my house, different circuits within the same building have trouble talking to each other, so I wouldn’t recommend that for cross-building communications...

  There were some small, low power AM radio stations that "transmitted" via power grid in mountain towns in North Carolina, a while back. I've been told that they had real trouble getting through transformers and they were using the main distribution lines and broadcast AM frequencies. That's with decent levels of power applied. I expect the incidental signals your usage generates are going to be hard to detect past your power meter and almost certainly un-resolvable past the distribution step down transformer.
