An app I was designing about six years back would have been something that some would use in their yard and others would use in a national park.

In the yard you have extreme latency. Sooner or later you'll get thirsty and you'll walk into WiFi distance.

In a national park there's no connectivity. You won't be able to get or receive anything until long after the moment has passed. None of the answers you get will be relevant anymore for most people (what percent of people who visit a national park visit the same one over and over again?).

Then I realized screen contrast wasn't 'there' yet so I shelved it, got busy, and there it remains collecting dust.
