OK, here are my immediate thoughts about solving the problem. It comes in two parts - setting up, and finding.
Setting up ...
* Take a photo of your front door (or where ever it is you're meeting),
* Include your lat/long,
* Create a unique, private ID (or URL of some sort),
* Share it.
Finding ...
* Point the app at the URL
* The app guides you to the lat/long
* The app displays how close you are, and the photo.
Is that what you do? If it's slick and usable then it could be really good. If it's something else that you do then it would be fascinating to see a compare-and-contrast.
