After discussing with David Faure on #kde-devel last night and this
morning, we can make a second interface (the plugin already uses
Q_INTERFACES anyway, so this is really easy) meaning that we would
have a class, let us call V2, and there would be 3 methods there (2
put, 1 delete http mehods).

We could do dynamic_cast from V1 to V2 since V2 inherits V1. I guess
that's simpler, if the code that needs delete/put is far away from the
plugin-loading code. It should work, since V1, V2 and the cast are all
defined in the same lib. We might want to have a non-inline destructor
in V1 and V2 though, to make sure (and making dynamic_cast only right
before calling put/delete, keep the V1 pointer for everything else).

I think it would not be that intrusive patch then. I can try to make
this patch as soon as possible, any objection to ?

Thank you for your time and help, Frederik ! :-)
