Well, my point was that if it really isn't legal to use Bing for some
reason and if quadkeys is only usable for Bing, then this patch is
only useful if you use it in a non-compliant way, which is something I
don't want to support.

Good luck ;-). I'm afriad that even if I read that I won't understand
all the legal implications it has...

Agree.

I'm not really afraid of that ;-). If there's nothing like "don't use
the Bing service in 3rd party libraries" and it looks it's possible to
use Bing legally, I have no problem with merging the patch and adding
support for Bing in libchamplain.

It would be useful to find if someone else uses the Bing maps too.
I've noticed Garmin uses it in it's Garmin Connect web interface but
so far I haven't seen it in any non-web application, which is why I'm
a bit skeptical if it's legal. Google for instance doesn't allow this.

Best,
Jiri
