Yeah, I was considering using an XAPI interface, but honestly I didn't
realize that was the only way allowable... I was just leaning that way
because of the larger area coverage allowed on a request. But yeah I agree
neither of these ideas are ideal.

Good find. I had skipped over mapquest open earlier for some reason, and
you're right it does work on that one. However I found some other route
attempts that would not work on mapquest but WOULD work on YOURS. How
confusing. See image here if you're curious.
Both attempts in that image work on BRouter, but it doesn't have a public
API, and it is really weird about starting the route far ahead of (or
behind) the actual point you give it (though at least still on the same

Thanks for your input anyway. I have the mapquest one working in my app
already... was very easy to set up. Just doesn't work for half the routes
I want it to. Considering having my application make both a mapquest open
AND a YOURS request, and then internally judge which one is better and
present that to the user.
