Hi co-metalworkers,

as you could read in Kevin's notes from the Solid BoF at Tokamak two days ago 
he planned to split up the architecture of Solid to allow for multiple 
backends. Timeframe was estimated to be somewhen after 4.5... seems yesterday 
he came back from the future and dropped a copy of that code into the current 
trunk. Being the one to do the UPnP backend* because of the experience by my 
network:/ kio-slave I had no choice to follow him and start to do my share the 
last hours, too. Without any future travels, sadly. But first success.

So the code is now in trunk and compiled and run by default. The UPnP backend 
currently uses the Coherence** server via D-Bus, so that is just a runtime 
dependency and will fail silently if no Coherence server with a compatible 
version or at all can be started/reached. Other backends should be possible.

The code used for wrapping the UPnP stuff is bascially result of the second 
Coherence/KDE sprint last autumn and only a few weeks ago got silently dropped 
by me into trunk for the use with the network:/ kio-slave from 
kdebase/runtime. There you should now also see any UPnP devices in your local 
network popping up. For now they simply forward to the presentation url if 
available (the address of the web interface for the device).

What we need now is someone to help Bart to complete the kio-slave*** to 
access the content of UPnP MediaServer devices, as he is busy with other 
stuff.

And then some people who designs nice interfaces (as in Solid API) for the 
control of UPnP InternetGateway devices (like for NAT traversal) and, as far 
as useful, for that of MediaServers. For all other kind of device types this 
might also be nice to have, but these two seem to be the most important.

For OpenSuse 11.2 pick the Coherence package "python-coherence" from 
obs://build.opensuse.org/GNOME (use software.opensuse.org), this works for me.

Those too lazy to try the bleeding edge see the attached screenshot of a local 
UPnP MediaServer showing up in the solidhardwarebrowser (HAL data missing due 
to not yet ported model/view code inside the program).

Cheers
Friedrich
