I think being able to upload and overlay a potential route onto the member locations map would be a good feature enabling users to see how many hosts and who those hosts are are along their route. It would make looking for hosts that much easier and could help those unsure of their route recalibrate if they wish to.

I have not logged in for a long, long time and much to my detriment I imagine :o) I have never hosted (no requests!) or been hosted through warmshowers.org though I have searched and broswed occasionally when away on two wheels. Even so, this a feature I would love to be able to use. I use bikeroutetoaster.com to plot potential routes, to push them over here onto the map would be great.

I see you are using Drupal, I have some experience with Drupal and have been looking into mapping with Drupal a fair bit recently. I would like to help out it if you need any support...
