This device looks interesting.  I found a more informative link at

What would be great is if places along the trail had them.  They could
buy them and charge a fee to use them (<$5).  This strategy is very
doable on the AT, but are there enough hiker friendly places along the
way on the PCT?  I figure I'd only need one every 300 - 400 miles so I'd
bet it could work in that respect.  Also do you think the economics
could work?  Are there enough hikers with digital cameras willing to pay
$5 for the service to make it worthwhile?
