Well it needs to tie to the user database, and I was assuming that
we would like to do it without making everybody change everything.
It's perfectly possible to do in rails, and when it is necessary
we can do it. It may even be a good idea once we have a new database
server to leave the GPX data on the old one for example.
Now if I could just manage to spend less time writing emails on this
subject and more time investigating solutions then something might
actually get done.

The daemon has been turned off again this morning and is probably
going to have to stay off for the forseeable future in order to keep
the lock contention under control.
