[coherence-dev] howto add custom services/devices

adding vendor defined actions and variables is very easy to add
via the backends.

You can see some example here:

Adding a complete new service needs a bit more work.

You need to subclass for example the MediaServer class

http://coherence-project.org/browser/trunk/Coherence/coherence/upnp/devices/media_server.py

create the necessary Service classes by copying for example

http://coherence-project.org/browser/trunk/Coherence/coherence/upnp/services/servers/connection_manager_server.py

and then instantiating the device yourself, like this

http://coherence-project.org/browser/trunk/Cadre/cadre/base.py#L97


This may do sound more difficult than it actually is. ;-)

If you could provide me with some more details we could us this to
create some skeleton code in the wiki to serve as an example for
further reference.

Frank
