I might just join in there. Will what you produce be GPL?

At the moment it's just a couple of scripts quickly thrown together to
produce the results. I've just printed off a quick lesson to 'XML
HttpRequest and AJAX' and am off to read it. This looks like the way to
output waypoints to create an uploadable file to my GPS.

I've not even thought about what I'm doing with this except for personal
interest and learning. I might just build a site with it and allow people to
create and save their own GPS maps. So at the moment the answer is "I don't
know" when it comes to GPL etc. I'm just thinking of creating the site, and
leaving it to generate some adsense revenue or something. I must read the
Google Map T&C's though.

However it'd be useful to have some brains on a project like this, as it's
not completely straight forward.

It looks like it'll be okay to create. I just need a bracket to put the GPS
on my handlebars.... But I want it to go on my forward tube, not my 'cross'
handle bars. i.e. I would prefer a vertical clamp, not a horizontal clamp.

Can't see the thread, do you have the actual title or/and thread date.
