What can I do with DLNA on an android smartphone? What can I do with DLNA on an android smartphone?

I understand it allows wireless streaming media, but beyond that I have trouble finding details.

Will DLNA enabled smartphones receive data from servers? Will I be able to hit "play" on my smartphone and listen to it on my DLNA enabled stereo?
An Android phone with DLNA should be able to both send and receive.  My Galaxy S uses an app called AllShare to manage it, and there are others like 2Player in the Market. I'm sure you could stream to your stereo.
