That would be a nice feature. +1

Yes, if MMA is able to pull content over DLNA I'd presume you should also be able to push content to MMA over DLNA.

I'm not sure I know what you mean. Are you saying you want MMA to serve as a local renderer so that MMW can push the music to MMA?

Right click on Player in MMW and you can select DLNA/UPnP Players on the network. MMA isn't shown, should it (ie. has the capability been build in).

If not I'd like to see this feature.
