Is it possible to have a plugin so foobar can detect and play files from a upnp server?
Another words can foobar act as a Upnp Client.

I have the same question. Is that an UPNP plugin to make Foobar an UPNP client?

I'm curious as well... I have been debating purchasing a storage link router to attach my external drives to... The one I'm interested in has UPnP streaming of audio/video, but I'm hesitant because I'm not sure how well this will integrate with foobar...
