Well, not really. I last weekend began to play with idea of a kind of ad-hoc routegadget for personal or small training group use. For viewing locally stored maps and gpx tracks (your hard drive) by drag dropping them on browser. Half baked demo here:
Finland only (for O club Rastivarsat):
You can geo-reference your map by panning & zooming to the place you map is from, drag drop there, drag corners until map fits right (you can drop gpx files to have better reference for calibration) then click on of the corner markers, copy text and use it to re-name the map file (jpg/png/gif) you calibrated on your had drive. Now every time you drop the file named with this funny name it goes straight to the right place, so it is easy to drop map and then pile of gpx files and see where they went. For ad-hoc personal or small training group use. None of the files gets uploaded to the web, map and gpx files stay on your own computer, so no need to worry about copyright/publish permissions if maps are not shared. No usernames, passwords, script installs or write permissions. And no need to show maps/tracks to anyone else. But you can share maps and gpx maps using shared cloud storage folders, so one (coach) can prepare training and map, kids upload their gpx tracks and everyone including coach can view and compare tracks. Or at least that's the idea. GPX animations and such are still missing, it now simply shows the track and nothing else.
To try it you can download this zip, extract files to your hard drive and from there drag-drop files to those yellow areas at top right corner of the page.
Feel free to try it out in you own trainings and with your own map images.
