Yes I did it. I finally found the time to integrate Platinum UPnP Server inside XBMC. This was officially released a few days ago. (I am c0diq btw ;-)). I did try to make XBMC show up in XP My Network Places when you have the UPnP UI Component installed. Unfortunately, XP relies heavily on multicast for it to work. I wrote a SSDP Proxy a while back and I changed it to forward broadcast messages to Multicast and vice-versa. When the Proxy is running on another machine than the XP box, it works great. But if it’s running on the same machine as the XP box, XP doesn’t receive the multicast packet. This is the same problem I have experienced with Windows Media Connect. If you try to look for it (using the Intel Tools) on the same machine, it won’t work. That’s because the UPnPHost (UPnP Windows implementation) refuses Multicast packets coming from the same machine. Yack.

So after 2 days of extreme frustration, I decided to switch gear. I am working now on a firefox extension called Fireball that will let you find upnp servers on the network and browse them via javascript. How cool is that!? I am 70% there. Say tuned!
I also just released version 0.3.7 on Sourceforge with lots of improvements and bug fixed. Usual place.
