Cheers yeah, I actually tried a bunch of those software KVMs with my previous keyboard. I’m limited to portable ones as I don’t have admin access to the work machine, and for whatever reason both the keyboard and mouse were laggy as hell when moving to the Mac with each one, although I think all the ones I tried were all actually forks of Synergy.
That was what prompted the change to a Bluetooth multi-device ergo keyboard. The K860 is superb, but I would like to eliminate the Mac connection delay if possible.
Much of the research I’ve done seems to suggest “that’s just the way it is on Mac”, but there were suggestions regarding switching off Handoff so I’ll give that a go in the morning and see if it makes any difference.

Mixed feelings about this.
However, ethical questions aside, and from a purely legal conformation standpoint, if the phone validates the user is over 18 and passes only that info as a token to whatever application or website requests it, then it's a good implementation. It means elimination of multiple validation requirements, minimal transfer of data to third parties, fewer sources holding personal data, etc. Whether it works that way remains to be seen.
