I am experiencing trouble when using .NET to connect to the JSON-RPC service using WebSockets. Operating System is Windows 8 CP and XBMC is v12 on Raspberry Pi (Alpha 4, OpenElec install) and on the machine itself (Nightly d9ce56e, 20120805).
When making a Windows 8 Metro application and using the MessageWebSocket class to connect to the XBMC instance, an time-out occures. I fired up Wireshark on my machine to capture the network traffic. I can see that a GET request reaches XBMC and beïng ACK-ed. Hower I do not receive any HTTP response, and the connection is not upgraded to use the WebSockets protocol. This results in a timeout on the client, because the server disconnects the session after a certain amount of time. I tried the same with Firefox 12.0 using JavaScript and there where no issues while both are using WebSockets v13. I also captured the firefox traffic, and I found some differences, see this screenshot (click for full size):

Code:
try
{
// Make a local copy to avoid races with Closed events.
MessageWebSocket webSocket = _webSocket;
// Have we connected yet?
if (webSocket == null)
{
webSocket = new MessageWebSocket();
// MessageWebSocket supports both utf8 and binary messages.
// When utf8 is specified as the messageType, then the developer
// promises to only send utf8-encoded data.
//webSocket.Control.MessageType = SocketMessageType.Utf8;
// Set up callbacks
webSocket.MessageReceived += MessageReceived;
webSocket.Closed += Closed;
await webSocket.ConnectAsync(server);
// Code below never reaced because connection fails
_webSocket = webSocket; // Only store it after successfully connecting.
_messageWriter = new DataWriter(webSocket.OutputStream);
}
}
catch (Exception ex) // For debugging
{
WebErrorStatus status = WebSocketError.GetStatus(ex.GetBaseException().HResult);
// Here Timeout catched after ~30 secs
}
Someone has an idea where it goes wrong? Looks like XBMC does not handle the WebSocket from .NET in the right way.
I didn't think about the "addon boundary" (nor the delay in downloading the information). Only a way to trigger the addon would already be great (combined with the "auto download sync subtible" setting would already make it work quite well), so I'll wait for some work in triggering addon.
