Server Software to stream Webcam to DLNA Digital Media Renderer

Question

Idea

I'm curious if it is possible to stream a webcam to an DLNA Digital Media Renderer...

Here's the idea:

• We have a webcam attached to a small server
  • running a DLNA Digital Media Server (DMS) (software?) streaming the webcam
  • running a DLNA Digital Media Controller (DMC) (software?) controlling the stream
• as soon as some motion is detected by the webcam
  • the DMC takes the video stream from the DMS an throws it to a DLNA Digital Media Renderer (DMR) (i.e. a fancy SmartTV)

IMHO this is similar to what happens, when you use iMediaShare to get a Youtube video on you SmartTV.

Motivation

Useful scenarios? Well, in MY case i want to add a video camera to a doorbell. And whenever someone rings and I'm watching TV, i see the video from the door. Additionally you can stream this to PCs and smartphones.

Why i need you

I hope you like the idea, too, and have some information for me. Anything will do, but i prefer Open Source and Linux stuff, for the sake of customisation. I will add all useful information to this thread, so you may follow up, if you want.

Sorry for the poor tagging, but i can't use DMC or DMS. Do you have ideas?

Programs

Can't post links due to rep... will wait -.-

• Coherence: Seems outdated?
• GUPnP: looks nice, lib only? seems to be very big, and i didn't find information to DMC
• Fuppes: Looks promising, but seems outdated. No DMC support?
• Cling: Looks promising, but lib only. After trying the Workbech I was able to control my TV. So this LIB will be checked for shure!
• Brisa: Looks promising and big.
• MiniDLNA: Seems it doesn't support what i want...
