HTTP-U (HTTP over UDP) is used for sending announcements to a multicast
address and to devices, SOAP is used for sending control packets, HTTP
is used for sending subscriptions and unsubscriptions and HTTP is also
used for receiving state changes. It is quite a mix of protocols :-)

Things I have found so far is that certain devices will only accept SOAP
if the XML namespaces are the same as in Windows XP/Vista, that certain
parameters have to have content (and where a single space will not
suffice), and so on (I am trying to document it).

Can you set that stuff in JOLIE?
