If you missed the announcement the other day, WebSockets are now supported in Windows Azure Web Sites.
Let's try it with a sample SignalR application.
Create an Azure Web Site
Create a Visual Studio Project associated to an Azure Web Site
Add SignalR Stock Ticker Sample
$.connection.hub.logging = true;
Publish your local changes to Azure Web Site
Enable WebSocket on Azure Web Site
It's a shame that it takes Windows 8 or WIndows Server 2012 to get websocket support in SignalR... shocking really!
