http://SendingOutAnSOS.com helps you develop a travel plan before you
set out. If you don't make it back by a pre-arranged date, we send an
SOS message containing your travel intentions to your loved ones (or
other contacts). Hopefully they will come to your rescue!

From the website:

3. When you get back, sign in to let us know you're safe.

Finding an Internet 'cafe' which was open was one of the biggest
problems during our recent (Feb) trip to Oz (WA). IMO not a practical
approach for rural/outback areas, which is probably where most of the
"trail"s are. (Yes, I realize that this is posted from a .nz address and
also to a European group, but 'even' there my comments are applicable.)

If you don't mind, I'll rely (sp?) on an EPIRB (satelite safety
beacon) instead.
