Given the fact we have slightly less ressources than Mandriva and that
people on Mandriva side ( or at least, that's what I remind that fcrozat
told me ) didn't have the ressources to have a more complex system, we
should avoid this.

You can use space in a url.
 
And if we use a XML-RPC api, we will not be able to change it either, so
that trading the impossibility of changing the format for the
impossibility to change the API.

This could be done on the client side. On the client side, this would
mean a little bit more bandwidth used, a little more cpu, and on our
side, it would be less CPU. And I think cpu is a more rare ressources
than bandwidth.

In fact, doing this on the client would be better on the privacy side.
