Is this issue solved in Openser 1.1.0 ?

As Daniel said on the ml thread :
it makes sense, we will analyze the implications
and include it on the
to-do list.
Cheers,
Daniel
Has it been included in the developpement branch yet ?

I'm not sure about the maddr parameter.
doesn't it mean that the request
should be forwarded to this IP regardsless of the domain? If yes, the
DNS lookup can be skipped.
